1 Kings 22:2-4

2Then it came about in the third year that King Jehoshaphat of Judah came down to the king of Israel.

3The king of Israel said to his courtiers, “Do you know that Ramoth-gilead is ours, yet we are still doing nothing to recover it from the hand of the king of Aram?”

4Then he said to Jehoshaphat, “Will you go with me to battle at Ramot-gilead?” Jehoshaphat said to the king of Israel, “I am as you are, my people as your people, my horses as your horses.”
