2 Chronicles 12:1, 5

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

Then came Shemaiah the prophet to Rehoboam, and to the princes of Judah, that were gathered together to Jerusalem because of Shishak, and said unto them, Thus saith the LORD, Ye have forsaken me, and therefore have I also left you in the hand of Shishak.
