em-bras': The word has two distinct meanings in the Old Testament:
(1) to clasp and hold fondly in the arms, pointing to a common custom (Ge 29:13;33:4;48:10;2Ki 4:16;So 2:6;8:3compareAc 20:10), and
(2) to have sexual intercourse (Pr 4:8;5:20;Ec 3:5). It seems to have acquired this technical sense in later Jewish usage.
