31 It happened, when the captains of the chariots saw Jehoshaphat, that they said, "It is the king of Israel!" Therefore they turned around to fight against him. But Jehoshaphat cried out, and Yahweh helped him; and God moved them to depart from him.

And the Lord helped him - There is nothing correspondent to this passage in Kings. It is a pious reflection on the part of the author, who traces all deliverance to its real divine source.
But Jehoshaphat cried out - "Jehoshaphat cried, and the Word of the Lord brought him assistance." - Targum.
And it came to pass, when the captains of the chariots saw Jehoshaphat, that they said, It [is] the king of Israel. Therefore they compassed about him to fight: but Jehoshaphat (t) cried out, and the LORD helped him; and God moved them [to depart] from him.
(t) He cried to the Lord by acknowledging his fault in going with this wicked king to war against the word of the Lord by his prophet and also by desiring mercy for the same.
Cried out - He cried out, either to his friends to help, or to his enemies, to let them know, he was not the king of Israel: or to God, and not in vain; for he moved the captains to depart from him. Many are moved in a manner unaccountable both to themselves and others; but an invisible power moves them.
