3:1-10 The call which Divine grace designs shall be made effectual; will be repeated till it is so, till we come to the call. Eli, perceiving that it was the voice of God that Samuel heard, instructed him what to say. Though it was a disgrace to Eli, for God's call to be directed to Samuel, yet he told him how to meet it. Thus the elder should do their utmost to assist and improve the younger that are rising up. Let us never fail to teach those who are coming after us, even such as will soon be preferred before us, Joh 1:30. Good words should be put into children's mouths betimes, by which they may be prepared to learn Divine things, and be trained up to regard them.
5-18. he ran unto Eli, and said, Here am I; for thou calledst me—It is evident that his sleeping chamber was close to that of the aged high priest and that he was accustomed to be called during the night. The three successive calls addressed to the boy convinced Eli of the divine character of the speaker, and he therefore exhorted the child to give a reverential attention to the message. The burden of [the Lord's message] was an extraordinary premonition of the judgments that impended over Eli's house; and the aged priest, having drawn the painful secret from the child, exclaimed, "It is the Lord; let him do what seemeth him good." Such is the spirit of meek and unmurmuring submission in which we ought to receive the dispensations of God, however severe and afflictive. But, in order to form a right estimate of Eli's language and conduct on this occasion, we must consider the overwhelming accumulation of judgments denounced against his person, his sons, his descendants—his altar, and nation. With such a threatening prospect before him, his piety and meekness were wonderful. In his personal character he seems to have been a good man, but his sons' conduct was flagrantly bad; and though his misfortunes claim our sympathy, it is impossible to approve or defend the weak and unfaithful course which, in the retributive justice of God, brought these adversities upon him.
