1 Kings 22:44

And they continued three years without war between Syria and Israel.

And it came to pass in the third year, that Jehoshaphat the king of Judah came down to the king of Israel.

And the king of Israel said unto his servants, Know ye that Ramoth in Gilead is our's, and we be still, and take it not out of the hand of the king of Syria?

And he said unto Jehoshaphat, Wilt thou go with me to battle to Ramoth-gilead? And Jehoshaphat said to the king of Israel, I am as thou art, my people as thy people, my horses as thy horses.
