Commentaries
2:27-36 Those who allow their children in any evil way, and do not use their authority to restrain and punish them, in effect honour them more than God. Let Eli's example excite parents earnestly to strive against the beginnings of wickedness, and to train up their children in the nurture and admonition of the Lord. In the midst of the sentence against the house of Eli, mercy is promised to Israel. God's work shall never fall to the ground for want of hands to carry it on. Christ is that merciful and faithful High Priest, whom God raised up when the Levitical priesthood was thrown off, who in all things did his Father's mind, and for whom God will build a sure house, build it on a rock, so that hell cannot prevail against it.
1Sa 2:27-35. A Prophecy against Eli's House.
27. there came a man of God unto Eli, and said … that there shall not be an old man in thine house—So much importance has always, in the East, been attached to old age, that it would be felt to be a great calamity, and sensibly to lower the respectability of any family which could boast of few or no old men. The prediction of this prophet was fully confirmed by the afflictions, degradation, poverty, and many untimely deaths with which the house of Eli was visited after its announcement (see 1Sa 4:11; 14:3; 22:18-23; 1Ki 2:27).
