15 Now the Lord had told Samuel the previous day, 16 "About this time tomorrow I will send you a man from the land of Benjamin. Anoint him to be the leader of my people, Israel. He will rescue them from the Philistines, for I have looked down on my people in mercy and have heard their cry." 17 When Samuel saw Saul, the Lord said, "That's the man I told you about! He will rule my people."

Commentary on 1 Samuel 9:11-17
(Read 1 Samuel 9:11-17)
The very maid-servants of the city could direct to the prophet. They had heard of the sacrifice, and could tell of the necessity for Samuel's presence. It is no small benefit to live in religious and holy places. And we should always be ready to help those who are seeking after God's prophets. Though God had, in displeasure, granted Israel's request for a king, yet he sends them a man to be captain over them, to save them out of the hand of the Philistines. He does it, listening graciously to their cry.
