Leviticus 4:35

4:35 Then the one who brought the offering ¹  must remove all its fat (just as the fat of the sheep is removed from the peace offering sacrifice) and the priest must offer them up in smoke on the altar on top of the other gifts of the Lord. So the priest will make atonement ²  on his behalf for his sin which he has committed and he will be forgiven. ³ 

Leviticus 10:15

10:15 The thigh of the contribution offering and the breast of the wave offering they must bring in addition to the gifts of the fat parts to wave them as a wave offering before the Lord, and it will belong to you and your sons with you for a perpetual statute just as the Lord has commanded.”

Leviticus 21:21

21:21 No man from the descendants of Aaron the priest who has a physical flaw may step forward ⁴  to present the Lord’s gifts; he has a physical flaw, so he must not step forward to present the food of his God.

[4:35]  ¹ tn Heb “Then he”; the referent has been specified in the translation for clarity. Here “he” refers to the offerer rather than the priest (contrast the clauses before and after).

[4:35]  ² sn The focus of sin offering “atonement” was purging impurities from the tabernacle (see the note on Lev 1:4).

[4:35]  ³ tn Heb “there shall be forgiveness to him” or “it shall be forgiven to him” (KJV similar).

[21:21]  ⁴ tn Or “shall approach” (see HALOT 670 s.v. נגשׁ).
