1 Kings 20:13, 22

And, behold, there came a prophet unto Ahab king of Israel, saying, Thus saith the LORD, Hast thou seen all this great multitude? behold, I will deliver it into thine hand this day; and thou shalt know that I am the LORD.

And the prophet came to the king of Israel, and said unto him, Go, strengthen thyself, and mark, and see what thou doest: for at the return of the year the king of Syria will come up against thee.
