Commentary on 1 Samuel 3:11

• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on 1 Samuel 3:11-18: Here is, I. The message which, after all this introduction, God delivered to Samuel concerning Eli's house. God did not come to him now to tell him how great a man he should be in his day, what a figure he should make, and what a blessing he should be in Israel.
• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on 1 Samuel 3:11: And the Lord said to Samuel,.... The voice of the Lord continued speaking to him: behold: I will do a thing in Israel; which may be particularly interpreted of the taking of the ark, and the slaying of the two sons of Eli; and which is elsewhere represented as the Lord's doing, for the sins of Eli's family, Psa 78:61.

• Adam Clarke (Methodist), Clarke's Commentary on the Bible on 1 Samuel 3:11: The Lord said to Samuel - He probably saw nothing, and only heard the voice; for it was not likely that any extraordinary representation could have been made to the eyes of a person so young. He heard a voice, but saw no similitude.
