Charles Ellicott Commentary 2 Chronicles 12:7

"And when Jehovah saw that they humbled themselves, the word of Jehovah came to Shemaiah, saying, They have humbled themselves: I will not destroy them; but I will grant them some deliverance, and my wrath shall not be poured out upon Jerusalem by the hand of Shishak." — 2 Chronicles 12:7 (ASV)

But I will grant them some deliverance. —Rather, and I will give them a few for a remnant. (Compare to 2 Chronicles 12:12, that he would not destroy him altogether.) For the phrase “to give a remnant,” see Ezra 9:13. The word rendered “few” is kim‘at. (Compare to 1 Chronicles 16:19; Isaiah 1:9.) The pointing kim‘ât is peculiar to this passage.

My wrath shall not be poured out. —Or, pour itself out, wreak itself. The phrase denotes a judgment of extermination. (Compare to its use in 2 Chronicles 34:25.)

By the hand of Shishak. —The destruction of Jerusalem was reserved for the hand of Nebuchadnezzar.
