Charles Ellicott Commentary 1 Samuel 2:30

"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." — 1 Samuel 2:30 (ASV)

... but now the Lord says, Be it far from me.

But the fulfillment of the glorious and gracious promise, which involved the walking of the favored house forever in the light of the Lord in the blessed courts of the sanctuary with no worldly cares—were they not amply provided for without sowing and reaping? Were they not invested with high honors and universal consideration?—was necessarily dependent upon those who walked, the favored house carrying out their share of the covenant.

To be honored by God, they, for their part, must be His faithful servants. Now, the life and conduct of the priestly house had caused the gravest dishonor and brought the deepest shame on the worship and sanctuary of the “King in Jeshurun.”
