1 Kings 20:22

And the prophet, the same one who had prophesied the defeat of the Syrians, came to the king of Israel and said unto him, Go, strengthen thyself, namely, by enlarging and equipping his army, and mark and see what thou doest, he was to be on his guard; for at the return of the year, at the close of the winter rains, when campaigns were usually commenced, the king of Syria will come up against thee.
