Leviticus 4:24

And he shall lay his hand upon the head of the goat
His right hand, as the Targum of Jonathan; (See Gill on Leviticus 1:4)

and kill it;
not the prince, but the priest after mentioned, or the butcher, as the same Targum:

in the place where they hill the burnt offering before the Lord;
in the court on the north side of the altar, see ( Leviticus 1:11 ) ( 6:25 ) :

it is a sin offering:
an offering for his sin of ignorance, or "sin"; so Christ our offering is said to be, ( 2 Corinthians 5:21 ) .
