This term is used three times in the:
(1) in 1Ki 3:1, where we read that "Solomon made affinity with Pharaoh King of Egypt",
(2) in 2Ch 18:1, where it is stated that Jehoshaphat "joined affinity with Ahab," and
(3) in Ezr 9:14, where it is asked "Shall we .... join in affinity with the peoples that do these abominations?" The Hebrew word thus rendered in the above three passages refers in each case to marriage alliances rather than to family or political relationships.
See Marriage; FAMILY.
