And thou {y} shalt see an enemy in my habitation, in all the wealth which God shall give Israel: and there shall not be an old man in thine house for ever.

(y) Your posterity will see the glory of the chief priest given to another, whom they will envy, 1Ki 2:27.

Wesley's Notes

2:32 Shalt see, and c - The words may be rendered; thou shalt see, in thy own person, the affliction, or calamity of my habitation; that is, either of the land of Israel, wherein I dwell; or of the sanctuary, called the habitation by way of eminency, whose greatest glory the ark was, 1Sam 4:21,22, and consequently, whose greatest calamity the loss of the ark was; for, or instead of all that good wherewith God would have blessed Israel, having raised up a young prophet Samuel, and thereby given good grounds of hope that he intended to bless Israel, if thou and thy sons had not hindered it by your sins. So this clause of the threatning concerns Eli's person, as the following concerns his posterity. And this best agrees with the most proper signification of that phrase, Thou shalt see.

King James Translators' Notes

an enemy...: or, the affliction of the tabernacle, for all the wealth which God would have given Israel

Jamieson-Fausset-Brown Bible Commentary

32. thou shalt see an enemy in my habitation-A successful rival for the office of high priest shall rise out of another family (2Sa 15:35; 1Ch 24:3; 29:22). But the marginal reading, "thou shalt see the affliction of the tabernacle," seems to be a preferable translation.

Matthew Henry's Concise Commentary

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.
