Longer answer than I intended, so sorry about that, but if you are really interested you will read it all.
As Wretched said, if you are looking for a 100% kind of thing, then you are looking to do without faith.
(6) But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
However, to address the three examples you cite:
First of all, we must confirm that you are talking about the KJV. Most of the other versions have some pretty gross errors in them, and the rest are less obvious but still notable.
Secondly, I am taking this as a genuine question, although these are the three most common “issues” that people bring up…….
Thirdly, if you take single verses in isolation, then it is very easy to become “disoriented” from the account. As a result, I will quote passages in most cases rather than single verses.
“Matthew 27:5 (Judas hanged himself) and Acts 1:18 (Judas died by falling down in a field)”
(4) Saying, I have sinned in that I have betrayed the innocent blood. And they said, What is that to us? see thou to that.
(5) And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.
(6) And the chief priests took the silver pieces, and said, It is not lawful for to put them into the treasury, because it is the price of blood.
(7) And they took counsel, and bought with them the potter's field, to bury strangers in.
(8) Wherefore that field was called, The field of blood, unto this day.
(18) Now this man purchased a field with the reward of iniquity; and falling headlong, he burst asunder in the midst, and all his bowels gushed out.
(19) And it was known unto all the dwellers at Jerusalem; insomuch as that field is called in their proper tongue, Aceldama, that is to say, The field of blood.
There are actually 2 issues with this passage: the one you mentioned (the manner of his death), and the purchase of the field.
Judas didn’t purchase the field, as Acts 1 18 says, but Matthew 27:7-8 tells us that the chief priests purchased the field – but they did so with the money they paid to Judas, so in effect they purchased it for him. Neither is in error. It was the money of Judas, and therefore he paid for it, although the transaction was not done by Judas himself, but on his behalf. I point this out, because it shows that things stated in different ways can correctly refer to the same event.
Now in regard to your actual issue with this passage, Matthew 27 tells us that Judas hanged himself. This would be the manner of his death.
Acts 1:18 doesn’t actually mention his death at all – you are assuming it is how he died, but the verses do not say that. If you look at the verse it says that he purchased the land, then fell over and his bowels gushed out. But if you look in Matthew 27 you see that he hanged himself, THEN the land was purchased in his name. Paupers who died in those days were thrown into a rubbish pile outside the city walls, and if he was dropped over the wall into that rubbish pile I would think that he would likely burst asunder and his bowels would gush out…… Of course, the money was used to buy “the Potter’s Field” so that practice (Bodies on the rubbish pile) should have ceased after Judas, for then there was a place to bury strangers in. But only after this event, for even in those days it would take time to find, purchase, and organise the land for this purpose.
The order of events, and an understanding of history is enough for us to address this "problem".
“1 Chron 21:5 vs. 2 Sam. 24:9 (number of fighting me in Isreal)”
(1) And Satan stood up against Israel, and provoked David to number Israel.
(2) And David said to Joab and to the rulers of the people, Go, number Israel from Beersheba even to Dan; and bring the number of them to me, that I may know it.
(3) And Joab answered, The LORD make his people an hundred times so many more as they be: but, my lord the king, are they not all my lord's servants? why then doth my lord require this thing? why will he be a cause of trespass to Israel?
(4) Nevertheless the king's word prevailed against Joab. Wherefore Joab departed, and went throughout all Israel, and came to Jerusalem.
(5) And Joab gave the sum of the number of the people unto David. And all they of Israel were a thousand thousand and an hundred thousand men that drew sword: and Judah was four hundred threescore and ten thousand men that drew sword.
(6) But Levi and Benjamin counted he not among them: for the king's word was abominable to Joab.
(7) And God was displeased with this thing; therefore he smote Israel.
One million one hundred thousand men in Israel (Northern Kingdom), and four hundred and seventy thousand men in Judah (Southern Kingdom).
(1) And again the anger of the LORD was kindled against Israel, and he moved David against them to say, Go, number Israel and Judah.
(2) For the king said to Joab the captain of the host, which was with him, Go now through all the tribes of Israel, from Dan even to Beersheba, and number ye the people, that I may know the number of the people.
(3) And Joab said unto the king, Now the LORD thy God add unto the people, how many soever they be, an hundredfold, and that the eyes of my lord the king may see it: but why doth my lord the king delight in this thing?
(4) Notwithstanding the king's word prevailed against Joab, and against the captains of the host. And Joab and the captains of the host went out from the presence of the king, to number the people of Israel.
(5) And they passed over Jordan, and pitched in Aroer, on the right side of the city that lieth in the midst of the river of Gad, and toward Jazer:
(6) Then they came to Gilead, and to the land of Tahtimhodshi; and they came to Danjaan, and about to Zidon,
(7) And came to the strong hold of Tyre, and to all the cities of the Hivites, and of the Canaanites: and they went out to the south of Judah, even to Beersheba.
(8) So when they had gone through all the land, they came to Jerusalem at the end of nine months and twenty days.
(9) And Joab gave up the sum of the number of the people unto the king: and there were in Israel eight hundred thousand valiant men that drew the sword; and the men of Judah were five hundred thousand men.
(10) And David's heart smote him after that he had numbered the people. And David said unto the LORD, I have sinned greatly in that I have done: and now, I beseech thee, O LORD, take away the iniquity of thy servant; for I have done very foolishly.
Eight hundred thousand in Israel, and five hundred thousand in Judah.
A seeming difference of three hundred thousand in Israel and thirty thousand in Judah.
My first thought is that in 1 Chron 21:6 it says that Joab didn’t count the Levites nor the Benjamites, so we would expect a difference in the numbers, with the 1 Chron 21 being the lower number, because it specifically says that some were not counted. That might explain the difference from Judah, but the difference in Israel is the wrong way for that simple explanation. We must therefore cast our net a little wider.
And we come to this passage:
(1) Now the children of Israel after their number, to wit, the chief fathers and captains of thousands and hundreds, and their officers that served the king in any matter of the courses, which came in and went out month by month throughout all the months of the year, of every course were twenty and four thousand.
It seems that there was a system of “reserves” called up each month 24000 from each tribe, which equals a total over the year of 288000.
For me, that is close enough to 300000 to make up the difference.
So Joab refused to count the Levites and the Benjamites – I assume they were associated with the Temple and with Jerusalem – I can happily assume that takes care of the 30000 of Judah missing from 1 Chron 21, and if the count from 2 Sam 24 didn’t include all those who were “already on the books” as it were as soldiers of the regular rotation, then we have a close enough number on the second figure to explain it as a “rounding to the nearest….”
“2 Chron 36:9 and 2 Kings 24:8 (was King Jehoiachin 8 years old or 18 when he was crowned).”
This is one of the most common issues we hear – I think that there is a thread from some time ago about this on this site…..
(8) Now the rest of the acts of Jehoiakim, and his abominations which he did, and that which was found in him, behold, they are written in the book of the kings of Israel and Judah: and Jehoiachin his son reigned in his stead.
(9) Jehoiachin was eight years old when he began to reign, and he reigned three months and ten days in Jerusalem: and he did that which was evil in the sight of the LORD.
(10) And when the year was expired, king Nebuchadnezzar sent, and brought him to Babylon, with the goodly vessels of the house of the LORD, and made Zedekiah his brother king over Judah and Jerusalem.
(6) So Jehoiakim slept with his fathers: and Jehoiachin his son reigned in his stead.
(7) And the king of Egypt came not again any more out of his land: for the king of Babylon had taken from the river of Egypt unto the river Euphrates all that pertained to the king of Egypt.
(8) Jehoiachin was eighteen years old when he began to reign, and he reigned in Jerusalem three months. And his mother's name was Nehushta, the daughter of Elnathan of Jerusalem.
(9) And he did that which was evil in the sight of the LORD, according to all that his father had done.
This at first seems like a problem, but in this case we need to look at the situation and see if we can find a solution.
In cases like this it would be easier for us if God made it super clear, but He does tell us to 2Ti 2:15
(15) Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
….so we really can’t complain if we have to put some effort in……
What was the situation in which he became “king”.
In the first place it is interesting that in 2 Chron 36 it says he was 8 when he began to reign in Jerusalem.
But in 2 Kings 24 it says he was 18 when he began to reign in Jerusalem.
Both accounts mention the same length of reign – I don’t see the 10 days being an issue.
In fact aside from the 8 vs 18 the only other difference is the mention of the mother in 2 Kings 24. The point about that is that in the passage which says he began to reign when he was 8 it doesn’t mention his father’s death, and in the passage where it mentions 18 and his mother, it specifically mentions his father’s death.
If you look at the situation of his father’s reign, you see Babylon was all around the place causing trouble and laying on pressure.
And in fact the last few verses 2 Kings 24 tells us that when Jehoiachin was taken to Babylon the Babylonian king put someone else as King over Jerusalem.
This is why he reigned only three months.
So is this an indication that Jehoiachin was appointed by his father as co-regent or heir in waiting? With the unsettled nature of the rule under Babylon (see the early part of that chapter), and the resultant replacement soon after Jehoiakim’s death, it is entirely reasonable to think that he may have appointed his son as co-regent in the hope that his claim to the throne would be established.
Therefore, he began to reign with his father at the age of 8, but began to reign in his own right 10 years later. In any case, he reigned only 3 months before he was taken by the Babylonians and put into a prison in Babylon, and another man put into the place of king instead of him, thereby proving his father’s wisdom in making him co-regent, but that not succeeding in its plan.
Now, none of these is a watertight answer, but each of them gives a satisfactory answer to the problems presented.
