And Samuel grew, and the LORD was with him, and did let none of his words fall to the ground.
And Samuel grew, and the Lord was with him - i:e., he advanced not only in age and physical stature, but in the acquirements of wisdom and piety; and the spiritual gifts with which he was so eminently endowed, showing as they did that he enjoyed the favour and blessing of God, secured him in consequence great influence with the people.
And did let none of his words fall to the ground - a metaphor derived from water being spilt on the ground (cf. Joshua 21:45; Esther 6:10), and signifying that none of Samuel's judgments were falsified by the event, but that all his predictions were fulfilled.
