“knew.” The word “know” is the common idiomatic word used for sexual intercourse. Sexual intercourse gives the most intimate and personal “knowledge” of the other, so “know” was used throughout the biblical world as an idiom for sexual intercourse (cp. Gen. 4:1, 17, 25; 24:16; Matt. 1:25), which even included rape (Gen. 19:5; Judg. 19:25). Other idioms for sexual intercourse are, “go into” (2 Sam. 3:7), and “go near; approach” (Exod. 19:15 ESV), “uncover the nakedness” (Lev. 18:12); and sometimes “see the nakedness” (Lev. 20:17).
