13 When you come into the town you will see him straight away, before he goes up to the high place for the feast: the people are waiting for his blessing before starting the feast, and after that the guests will take part in it. So go up now and you will see him.
Matthew Henry's Commentary on 1 Samuel 9:13
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.
