1 Samuel 9:17 (KJV)

Now the Lord had told Samuel in his ear a day before Saul came, saying,

To morrow about this time I will send thee a man out of the land of Benjamin, and thou shalt anoint him to be captain over my people Israel, that he may save my people out of the hand of the Philistines: for I have looked upon my people, because their cry is come unto me.

And when Samuel saw Saul, the Lord said unto him, Behold the man whom I spake to thee of! this same shall reign over my people.

Then Saul drew near to Samuel in the gate, and said, Tell me, I pray thee, where the seer’s house is.

And Samuel answered Saul, and said, I am the seer: go up before me unto the high place; for ye shall eat with me to day, and to morrow I will let thee go, and will tell thee all that is in thine heart.
