'Offering' in the Bible

And the sin of the young men is very great in the presence of Jehovah, for the men have despised the offering of Jehovah.

Why do ye kick at My sacrifice, and at Mine offering which I commanded in My habitation, and dost honour thy sons above Me, to make yourselves fat from the first part of every offering of Israel, of My people?

and therefore I have sworn to the house of Eli: the iniquity of the house of Eli is not atoned for, by sacrifice, and by offering -- unto the age.'
