Leviticus 3:2

And he shall lay his hand upon the head of his offering
"His right hand with strength", the Targum of Jonathan says; perhaps both his hands were imposed; the Septuagint and Arabic versions read it in the plural number, "hands"; this same rite was used in the sacrifice of burnt offering, (See Gill on Leviticus 1:4); which might be done in any place in the court where it was slain, only with this difference: according to Maimonides ^F4, there was no confession of sin made at laying on of hands upon the peace offerings, but words of praise were spoken:

and kill it at the door of the congregation;
it seems as if it was not the priest, but the owner that brought it, and laid his hands on it, that killed it; and so the last mentioned writer says, that slaying the peace offering by a stranger was right; and as he and others ^F5 say, it might be slain in any part of the court; it was not obliged to be slain in the north part of it, as the burnt offering was, ( Leviticus 1:11 )

and Aaron's sons the priests shall sprinkle the blood upon the
altar round about;
in like manner as the blood of the burnt offering was, and it was done with two sprinklings, which were as four {f}; (See Gill on Leviticus 1:5) this was typical of the blood of Christ, called "the blood of sprinkling".
