V.11 We don’t know how old Samuel was at this time but he was a boy. The Lord tells Samuel that what He was going to do would make everyone’s ears tingle! The Lord waited long, but Eli did not correct his guilty sons, nor did they turn from their wicked ways. God may wait patiently, but he will not overlook sin.
V.12-14 The Lord said He would do this. Take time to read in 1 Kings 2:27 what happened about 120 years later. Does God say something and not carry it out?
V.15-20 Samuel tells the whole message to Eli, and though Eli submitted to it, he didn’t seem to feel responsible to correct his guilty sons, even then.
V.21 And it was in Shiloh, the one place the Lord had chosen to set His Name. The Lord will reveal Himself to a believer today who is willing to hear and obey. Notice carefully how the Lord reveals Himself.
