1 Kings 22:4

4 Then he turned to Jehoshaphat and asked, “Will you join me in battle to recover Ramoth-gilead?” Jehoshaphat replied to the king of Israel, “Why, of course! You and I are as one. My troops are your troops, and my horses are your horses.”

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 Then during the third year, King Jehoshaphat of Judah went to visit King Ahab of Israel.

3 During the visit, the king of Israel said to his officials, “Do you realize that the town of Ramoth-gilead belongs to us? And yet we’ve done nothing to recapture it from the king of Aram!”

4 Then he turned to Jehoshaphat and asked, “Will you join me in battle to recover Ramoth-gilead?” Jehoshaphat replied to the king of Israel, “Why, of course! You and I are as one. My troops are your troops, and my horses are your horses.”

5 Then Jehoshaphat added, “But first let’s find out what the LORD says.”

6 So the king of Israel summoned the prophets, about 400 of them, and asked them, “Should I go to war against Ramoth-gilead, or should I hold back?” They all replied, “Yes, go right ahead! The Lord will give the king victory.”
