1 Kings 22:2-4

2Then it came to pass, in the third year, that Jehoshaphat the king of Judah went down to visit the king of Israel.

3And the king of Israel said to his servants, “Do you know that Ramoth in Gilead is ours, but we hesitate to take it out of the hand of the king of Syria?”

4So he said to Jehoshaphat, “Will you go with me to fight at Ramoth Gilead?” Jehoshaphat said to the king of Israel, “I am as you are, my people as your people, my horses as your horses.”
