Our church is currently working through Psalm 119 as our Bible study on Wednesday evenings.
Psalm 119:44
So shall I keep thy law continually for ever and ever.
It pays to look up every word! I work my way through each word in the verse, checking the Hebrew words to see what they mean. In English we use the phrase "forever and ever" to just mean ongoing, to just emphasize that we mean "always." So, I went to look up the first "ever" and assumed they would both be the same Hebrew word. They weren't.
ever = H5769 "olam" properly, concealed; that is, the vanishing point
ever = H5703 "ad" (as in ad infinitum) properly a (peremptory) terminus; that is (by implication) duration, in the sense of perpetuity
So when I looked up both words it indicates that the distance/time period talked about here it to the point that can no longer be seen, and past that, it keeps going, which immediately brought to mind Buzz Lightyear in Toy Story where his call to arms is "To Infinity and Beyond!"
I will always see "for ever and ever" in scripture now as "To Infinity and Beyond" lol.
It's the little things that make scripture meaningful and memorable.
