2 Chronicles 18:31

saw Jehoshaphat … to fight Render, saw Jehoshaphat, (now they said, It is the king of Israel!) that they turned about against him to fight. The captains of the chariots obeying the orders given them made a circuit in order to reach the rear of the Israelite army where Jehoshaphat was stationed. The same fact is described in 1 Kin. by the phrase, they turned aside. The A.V. of Chronicles they compassed about him(i.e. "surrounded him"; cp. 2 Chronicles 21:9) is a possible, but less probable, interpretation.

and God moved themto depart from him These words anticipate 2 Chronicles 18:32 and are not found in 1 Kin. Probably a panic fell on the Syrian charioteers when they found themselves far from the rest of the Syrian army and yet not near the king of Israel.
