Charles Ellicott Commentary 2 Chronicles 6:23

"then hear thou from heaven, and do, and judge thy servants, requiting the wicked, to bring his way upon his own head; and justifying the righteous, to give him according to his righteousness." — 2 Chronicles 6:23 (ASV)

From heaven. — In Kings, we do not have the preposition. Perhaps the meaning there is “to heaven,” as in 2 Chronicles 6:30. The chronicler has substituted a more ordinary expression, which, indeed, is found in all the versions of Kings. Similarly in 2 Chronicles 6:25; 2 Chronicles 6:30; 2 Chronicles 6:33; 2 Chronicles 6:35; 2 Chronicles 6:39.

By requiting the wicked. — So as to requite a wicked man. Kings, “so as to find guilty” (also the Syriac here). The latter is probably original. “To find guilty a guilty man” corresponds to “justifying a just one,” in the next clause.

By justifying. — So as to justify; or pronounce righteous.
