Tilgath-pilneser - This form of the name is doubly corrupt. See the properly Hebraized form in 2 Kings 15:29.
Distressed him, but strengthened him not - This statement, and that at the end of 2 Chronicles 28:21, is supplemental to, and not contradictory of, 2 Kings 16:9. Here it is the writer’s object to note that the material assistance rendered by Tiglath-pileser to Ahab, was no real “help” or “strength,” but rather a cause of “distress.”
