2 Chronicles 12:4

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.

And it came to pass, that in the fifth year of king Rehoboam Shishak king of Egypt came up against Jerusalem, because they had transgressed against the LORD,

With twelve hundred chariots, and threescore thousand horsemen: and the people were without number that came with him out of Egypt; the Lubims, the Sukkiims, and the Ethiopians.

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.
