1 Kings 22:4

Ver. 4 And he said unto Jehoshaphat, wilt thou go with me to battle
to Ramothgilead?
&c.] This affair being lately canvassed at the council board, and very much on Ahab's mind, he puts this question to Jehoshaphat, his visitor, relation, and ally; wisely considering that his own forces were small, and that to have such an auxiliary might be of great advantage to him:

and Jehoshaphat said to the king of Israel, I am as thou art, my people
as thy people, my horses as thy horses;
meaning, that he and his soldiers, foot and horse, were at his service.
