1 Kings 22:4 Meaning and Commentary

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.

1 Kings 22:4 In-Context

2 In the third year, Jehoshaphat king of Judah had a meeting with the king of Israel.
3 Israel's king remarked to his aides, "Do you realize that Ramoth Gilead belongs to us, and we're sitting around on our hands instead of taking it back from the king of Aram?"
4 He turned to Jehoshaphat and said, "Will you join me in fighting for Ramoth Gilead?"
5 He then continued, "But before you do anything, ask God for guidance."
6 The king of Israel got the prophets together - all four hundred of them - and put the question to them: "Should I attack Ramoth Gilead? Or should I hold back?" "Go for it," they said. "God will hand it over to the king."
