Imamat 4:4

4:4 He must bring the bull to the entrance of the Meeting Tent before the Lord, lay his hand on the head of the bull, and slaughter the bull before the Lord.

Imamat 4:29-31

4:29 He must lay his hand on the head of the sin offering and slaughter ¹  the sin offering in the place where the burnt offering is slaughtered. 4:30 Then the priest must take some of its blood with his finger and put it on the horns of the altar of burnt offering, and he must pour out all the rest of its blood at the base of the altar. 4:31 Then he must remove all of its fat (just as fat was removed from the peace offering sacrifice) and the priest must offer it up in smoke on the altar for a soothing aroma to the Lord. So the priest will make atonement ²  on his behalf and he will be forgiven. ³ 

[4:29]  ¹ tc The LXX has a plural form here (see v. 24 above and the note on Lev 1:5a).

[4:31]  ² sn The focus of sin offering “atonement” was purging impurities from the tabernacle (see the note on Lev 1:4).

[4:31]  ³ tn Heb “there shall be forgiveness to him” or “it shall be forgiven to him” (KJV similar).
