Charles Spurgeon Commentary 2 Chronicles 12:5

"Now Shemaiah the prophet came to Rehoboam, and to the princes of Judah, that were gathered together to Jerusalem because of Shishak, and said unto them, Thus saith Jehovah, Ye have forsaken me, therefore have I also left you in the hand of Shishak." — 2 Chronicles 12:5 (ASV)

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.

The prophet gave them no invitation to repentance; but just an explanation of the sorrow which had come upon them.
