Leviticus 1:5
4 He must lay his hand on the head of the burnt offering, and it will be accepted for him to make atonement on his behalf. 5 Then the one presenting the offering must slaughter the bull before the Lord, and the sons of Aaron, the priests, must present the blood and splash the blood against the sides of the altar, which is at the entrance of the Meeting Tent. 6 Next, the one presenting the offering must skin the burnt offering and cut it into parts,
LXX Leviticus 1:5
4 And he will place his hand on the head of the approved burnt offering for himself in order to make atonement for him 5 And they will slay the young bull in the presence of the Lord and the sons of Aaron, the priests. They will present its blood, and they will pour its blood out all around and against the altar that is beside the entrances of the tent of testimony 6 And when they have flayed the whole burnt offering, they will cut it into pieces according to its limbs
Notes and References
"... The plural, harmonized with the other plurals in the context, likely reflects the following concern: in the Masoretic text, the slaughter of the victim is attributed to the offerer and not to the priest. However, this is a characteristic perspective of the priestly tradition (P), according to which the slaughter is not the central moment of the sacrifice. The Septuagint (and the Samaritan Pentateuch) contains the same reading in verses 6 and 9, where even the number of the noun is modified, as well as in verses 11 (not in the Samaritan Pentateuch), 12, and 13. The change, likely due to theological considerations, is attested in various textual traditions and was probably already present in the Vorlage of the Septuagint ..."
