SEV Biblia, Chapter 3:14 Y por tanto yo he jurado a la casa de Elí, que la iniquidad de la casa de Elí no será expiada jamás, ni con sacrificios ni con presentes.
Clarke's Bible Commentary - 1 Samuel 3:14 Verse 14. Shall not be purged with sacrifice nor offering] That is, God was determined that they should be removed by a violent death. They had committed the sin unto death; and no offering or sacrifice could prevent this. What is spoken here relates to their temporal death only.
John Gill's Bible Commentary Ver. 14. And therefore I have sworn unto the house of Eli , etc.] Either had done this before, which was signified to him by the man of God, or did swear now for the confirmation of his threatenings, and to assure the certain performance of them: that the iniquity of Eli’s house shall not be purged with sacrifice nor offering for ever : not even typically, which was all that legal sacrifice could do; and not so that the priesthood should ever return to the family again, as the office of high priesthood never did; or, as Abarbinel interprets it, because of sacrifice and offering, that the iniquity Eli’s sons were guilty of in taking the flesh of the sacrifices and offerings, which did not belong to them, and before the Lord had his part, should never be expiated.
Matthew Henry Commentary Verses 11-18 - What a great deal of guilt and corruption is there in us, concernin which we may say, It is the iniquity which our own heart knoweth; we are conscious to ourselves of it! Those who do not restrain the sins of others, when it is in their power to do it, make themselves partaker of the guilt, and will be charged as joining in it. In his remarkabl answer to this awful sentence, Eli acknowledged that the Lord had right to do as he saw good, being assured that he would do nothin wrong. The meekness, patience, and humility contained in those words show that he was truly repentant; he accepted the punishment of his sin.
