King Solomon, son of King David and Bathsheba, is renowned in the Old Testament for his God-given wisdom, writing, wealth, and women. King of the United Monarchy of Judaea and Israel, the most often mentioned wife of Solomon is the daughter of the Egyptian pharaoh, but Solomon cemented alliances with the other neighboring Moabite, Ammonite, Edomite, Zidonian, and Hittite monarchs by marriage to their eligible young women whose polytheistic religious practices Solomon allowed. According to I Kings 11, in the Old Testament, Solomon had hundreds of wives and hundreds of concubines. The round numbers listed in the passage from I Kings 11 is a clue to the fact that it is an approximation.
Passage from I Kings 11 (KJV)
11:1 But king Solomon loved many strange women, together with the daughter of Pharaoh, women of the Moabites, Ammonites, Edomites, Zidonians, and Hittites:
11:2 Of the nations concerning which the LORD said unto the children of Israel, Ye shall not go in to them, neither shall they come in unto you: for surely they will turn away your heart after their gods: Solomon clave unto these in love.
11:3 And he had seven hundred wives, princesses, and three hundred concubines: and his wives turned away his heart.
