Albert Barnes Commentary 1 Samuel 2:17

"And the sin of the young men was very great before Jehovah; for the men despised the offering of Jehovah." — 1 Samuel 2:17 (ASV)

The offering of the Lord - Minchah, here in the general sense of “gift or offering” to God (Malachi 3:3). In its restricted sense, it is used of the meat offerings, the unbloody sacrifices, and is then coupled with bloody sacrifices, which are sacrifices of slain beasts (See 1 Samuel 2:29).
