1st Samuel 2:29 Wherefore kick ye at my sacrifice and at mine offering, which I have commanded in my habitation; and honourest thy sons above me, to make yourselves fat with the chiefest of all the offerings of Israel my people?
[Patriarchs & Prophets pp 576] The sacrifices, pointing forward to the death of Christ, were designed to preserve in the hearts of the people faith in the Redeemer to come; hence it was of the greatest importance that the Lord's directions concerning them should be strictly heeded. The peace offerings were especially an expression of thanksgiving to God. In these offerings the fat alone was to be burned upon the altar.
A certain specified portion was reserved for the priests, but the greater part was returned to the offerer, to be eaten by him and his friends in a sacrificial feast. Thus all hearts were to be directed, in gratitude and faith, to the great Sacrifice that was to take away the sin of the world. The sons of Eli, instead of realizing the solemnity of this symbolic service, only thought how they could make it a means of self-indulgence. Not content with the part of the peace offerings allotted them, they demanded an additional portion.
And the great number of these sacrifices presented at the annual feasts gave the priests an opportunity to enrich themselves at the expense of the people. They not only demanded more than their right, but refused to wait even until the fat had been burned as an offering to God. They persisted in claiming whatever portion pleased them, and, if denied, threatened to take it by violence.
1st Samuel 2:30 Wherefore the Lord God of Israel saith, I said indeed that thy house, and the house of thy father, should walk before me for ever: but now the Lord saith, Be it far from me; for them that honor me I will honor, and they that despise me shall be lightly esteemed.
May God add His blessing to the study of His word. “Good night” and God bless!
