1 Kings 11:1-4

Now King Solomon loved many foreign women. Besides Pharaoh’s daughter, he married women from Moab, Ammon, Edom, Sidon, and from among the Hittites. The LORD had clearly instructed the people of Israel, “You must not marry them, because they will turn your hearts to their gods.” Yet Solomon insisted on loving them anyway. He had 700 wives of royal birth and 300 concubines. And in fact, they did turn his heart away from the LORD. In Solomon’s old age, they turned his heart to worship other gods instead of being completely faithful to the LORD his God, as his father, David, had been.
