II Chronicles 12:1, 5

Now it came to pass, when Rehoboam had established the kingdom and had strengthened himself, that he forsook the law of the LORD, and all Israel along with him.

Then Shemaiah the prophet came to Rehoboam and the leaders of Judah, who were gathered together in Jerusalem because of Shishak, and said to them, “Thus says the LORD: ‘You have forsaken Me, and therefore I also have left you in the hand of Shishak.’ ”
