Surely it is the king of Israel - This was a natural supposition, as Jehoshaphat alone wore royal robes.
And Jehoshaphat cried out - Jehoshaphat called to his men for help, using perhaps his own special battle-cry, which would be distinct from that of Ahab, and would probably be known to the Syrians.
And it came to pass, when the captains of the chariots saw Jehoshaphat, that they said, Surely it [is] the king of Israel. And they turned aside to fight against him: and Jehoshaphat (x) cried out.
(x) That is, to the Lord for help.
And it came to pass, when the captains of the chariots saw Jehoshaphat,.... In his royal robes:
that they said, surely it is the king of Israel; for they might not know the persons either of Ahab or him, but judged by his habit:
and they turned aside to fight against him; pressed upon him with all their force, either to take him or slay him:
and Jehoshaphat cried out; with a loud voice, either to the captains to let them know who he was, or to his men to come to his assistance, or rather to God to help and deliver him; since it is said in 2-Chronicles 18:31 that the Lord helped him, and moved or inclined the hearts of the captains to depart from him, as it follows here.
