Samuel
1 Samuel 3:1BSB·traditional attribution

And the boy Samuel ministered to the LORD before Eli. Now in those days the word of the LORD was rare, and visions were scarce.

Matthew Henry Presbyterian @wholebiblehenry

To make way for the account of God's revealing himself first to Samuel, we are here told, 1. How industrious Samuel was in serving God, according as his place and capacity were (Sa1 3:1): The child Samuel, though but a child, ministered unto the Lord before Eli. It was an aggravation of the wickedness of Eli's sons that the child Samuel shamed them.

John Gill Reformed Baptist @doctorgill

And the child Samuel ministered unto the Lord before Eli,.... Under his direction and instruction; the Targum is, in the life of Eli, and in such parts of service, relating to the tabernacle of the Lord, as he was capable of, such as opening and shutting the doors of it, lighting the lamps, singing the praises of God, &c.

Geneva Bible Notes Reformed @genevanotes

And the child Samuel ministered unto the LORD before Eli. And the word of the LORD was precious in those days; [there was] no open vision. (a) The Chaldee text reads "while Eli lived". (b) Because there were very few prophets to declare it.
