1 Kings 22:2

And they continued three years without war between Syria and 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.

And Jehoshaphat said unto the king of Israel, Enquire, I pray thee, at the word of the LORD to day.
