Albert Barnes 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)

Be it far from me - The phrase so rendered is a favorite one in the Books of Samuel, where it occurs ten or eleven times. It is variously rendered in the King James Version as “God forbid,” and “Be it far from me, you, etc.” Literally, it means, “Be it an abomination to me.”
