What does 1 Samuel 3:9 mean?
God had condemned Eli for putting his sons above God. Instead of removing them from the priesthood, the high priest of Israel had allowed them to stay in their positions and continue to scorn the sacrifices by taking the best cuts for themselves (1 Samuel 2:29).When it came to Samuel, though, Eli seems to have been sensitive to the working of the Lord in the boy's life. His blessing of Hannah's request of the Lord has been used by God, in some part, to bring about Samuel's birth (1 Samuel 1:17). He had continued to offer blessings on behalf of Samuel's parents (1 Samuel 2:20–21), also used by God to bring them more children.
Now Eli has recognized that the voice Samuel keeps hearing call his name is the Lord Himself (1 Samuel 3:4–8). The old priest tells the boy what to do next time the Lord calls him. Samuel should ask God to speak, affirming that he, God's servant, is listening. Samuel returns to bed to wait.
