Clarke's Bible Commentary - 1 Samuel 3:19 Verse 19. Samuel grew] Increased to manhood.
The Lord was with him] Teaching him, and filling him with grace and holiness.
None of his words fall] Whatever prediction he uttered, God fulfilled it; and his counsels were received as coming from the Lord.
John Gill's Bible Commentary Ver. 19. And Samuel grew , etc.] Not only in years and stature, but in grace and goodness, in wisdom, knowledge, and understanding, both with respect to things natural and spiritual, and in esteem, credit, and reputation among men: and the Lord was with him ; he was not only in favour with men, but with God; and had fresh and repeated tokens of the grace and good will of God towards him; he indulged him with his presence, and assisted him in his service, and prospered and succeeded him in all things in which he was engaged. The Targum is, “the Word of the Lord was his help;” the essential Word of God, the Messiah: and did let none of his words fall to the ground f75 ; in allusion either to water that falls to the ground, and becomes useless, or to an arrow falling out of the bow, and to the ground, before it reaches the mark, and so unsuccessful f76 ; or to any weapon of war, sword or spear, falling out of the hand of the soldier, whereby he is disarmed and rendered unserviceable: and these words, according to Kimchi, and in which he is followed by Abarbinel, are to be understood, not only of the words which he spake by the Holy Ghost under a spirit of prophecy, and had their exact accomplishment; but his common words, which were spoken by weight and measure, as the last expresses it, and which were delivered out according to the rules of justice, probity, and truth; and so he failed not of performing that which he had said, or of doing what was right, whereby Israel knew he was fit, prepared, and designed to be a prophet of the Lord, as in the following verse; but it seems rather to have respect to the things predicted by him under a spirit of prophecy concerning Eli and his house, which soon began to be fulfilled.
Matthew Henry Commentary Verses 19-21 - All increase in wisdom and grace, is owing to the presence of God with us. God will graciously repeat his visits to those who receive the aright. Early piety will be the greatest honour of young people. Thos who honour God he will honour. Let young people consider the piety of Samuel, and from him they will learn to remember their Creator in the days of their youth. Young children are capable of religion. Samuel in a proof that their waiting upon the Lord will be pleasing to him. He is a pattern of all those amiable tempers, which are the brightes ornament of youth, and a sure source of happiness __________________________________________________________________
