"The man had relations with his wife Eve, and she conceived and bore Cain, saying, ‘I have produced a man with the help of the LORD.’" (NAB)

Genesis 4:1
Why have I listed five versions of the same verse? I believe they demonstrate differing viewpoints on translational accuracy in the Bible. The first three more clearly convey in modern language what Adam and Eve did. On the other hand, the last one maintains more of the meanings found in the Hebrew. (I do not mean this as an apologia for the ESV. I’m well aware of the many faults that are not apparent in this particular verse. ) "To know" is idiomatic and obviously denotes sexual intercourse. It means more than that, though. It connotes intimacy and the notion of becoming "one flesh". "Cain" sounds like the Hebrew for "gotten". Strangley, more of the translations maintain this parallel. But I digress; it is "to know" that interests me today.
