30 Therefore Jehovah, the God of Israel, saith, I said indeed that thy house, and the house of thy father, should walk before me for ever: but now Jehovah saith, Be it far from me; for them that honor me I will honor, and they that despise me shall be lightly esteemed. 31 Behold, the days come, that I will cut off thine arm, and the arm of thy father's house, that there shall not be an old man in thy house. 32 And thou shalt behold the affliction of [my] habitation, in all the wealth which [God] shall give Israel; and there shall not be an old man in thy house for ever. 33 And the man of thine, [whom] I shall not cut off from mine altar, [shall be] to consume thine eyes, and to grieve thy heart; and all the increase of thy house shall die in the flower of their age. 34 And this shall be the sign unto thee, that shall come upon thy two sons, on Hophni and Phinehas: in one day they shall die both of them. 35 And I will raise me up a faithful priest, that shall do according to that which is in my heart and in my mind: and I will build him a sure house; and he shall walk before mine anointed for ever. 36 And it shall come to pass, that every one that is left in thy house shall come and bow down to him for a piece of silver and a loaf of bread, and shall say, Put me, I pray thee, into one of the priests' offices, that I may eat a morsel of bread.

Matthew Henry's Commentary on 1 Samuel 2:30-36

Commentary on 1 Samuel 2:27-36

(Read 1 Samuel 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.
