In the Bible we can count 15 examples of polygamy from the time of Lamech to 931 A.D. 13 of these men had enough power that no one could call into question their practice, they were unaccountable or no one dared approach them. Lamech Genesis 4:19; Abraham Genesis 16; Esau Genesis 26:34; 28:9; Jacob Genesis 29:30; Ashur 1 Chronicles 4:5; Gideon Judges 8:30; Elkanah 1 Samuel 1:2; David 1 Samuel 25:39-44; 2 Samuel 3:2-5; 5:13; 1 Chronicles 14:3; Solomon 1 Kings 11:1-8; Rehoboam 2 Chronicles 11:18-23; Abijah 2 Chronicles 13:21; Jehoram 2 Chronicles 21:14; Joash 2 Chronicles 24:3; Ahab 2 Kings 10; Jehoiachin 2 Kings 24:15; Belshazzar Daniel 5:2; 1 Chronicles 2:8; Hosea in Hosea 3:1,2. Polygamy is mentioned in the Mosaic law and made inclusive on the basis of legislation, and continued to be practiced all down through the period of Jewish history to the Captivity, after which there is no instance of it on record (Gen.29:15-30, Jacob and his wives.)
