2 Chronicles 20:35 Meaning and Commentary

2 Chronicles 20:35

And after this did Jehoshaphat king of Judah join himself with
Ahaziah king of Israel
Meaning, not after the invasion of the Moabites and the slaughter of them, but after Jehoshaphat returned from Ramothgilead, when he was reproved by a prophet for helping the ungodly, ( 2 Chronicles 19:1 2 Chronicles 19:2 ) so that it was a great aggravation of his folly and weakness, that after that, and quickly after that, he should join himself to a wicked prince, though not in war, but in trade; for so it must be, since Ahaziah reigned but two years, and those not complete, see ( 1 Kings 22:51 ) , but is here related, that Jehoshaphat's weaknesses and blemishes might be laid together:

who did very wickedly;
that is, Ahaziah, who walked in the ways of Ahab his father, and of Jezebel his mother, and of Jeroboam the son of Nebat, ( 1 Kings 22:52 ) .
