13 As soon as you enter the town, you will find him, before he goes up to the shrine to eat. For the people will not eat until he comes, since he must bless the sacrifice; afterward those eat who are invited. Now go up, for you will meet him immediately."

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.
