Leviticus 6:25

25 Speak thou to Aaron and to his sons, This is the law of sacrifice for sin; it shall be offered before the Lord, in the place where burnt sacrifice is offered; it is holy of holy things. (Say thou to Aaron and his sons, This is the law for the sin offering; it shall be offered before the Lord, in the place where the burnt sacrifice is offered; it is a most holy, or sacred, thing.)

Leviticus 6:25 Meaning and Commentary

Leviticus 6:25

Speak unto Aaron, and to his sons, saying, this [is] the
law of the sin [offering]
Or the rules to be observed concerning that, besides what had been already delivered in ( Leviticus 4:1-35 ) :

in the place where the burnt offering is killed shall the sin
[offering] be killed before the Lord;
and that was on the north side of the altar, see ( Leviticus 1:11 ) and so Aben Ezra and Ben Gersom observe, that the place of slaying every sin offering was the north; and some have observed that Mount Calvary, where our Lord was crucified, lay pretty much to the north of Jerusalem, see ( Psalms 48:2 ) :

it is most holy;
sacred to the Lord, offered up to him, and accepted by him, and typical of the most pure and holy sacrifice of Christ, who was made sin, and an offering for sin, in the room and stead of his people.

Leviticus 6:25 In-Context

23 For all the sacrifice of priests shall be burnt with fire, neither any man shall eat thereof. (For all of the grain offering of a priest shall be burned with fire, no one shall eat any of it.)

24 And the Lord spake to Moses, and said,

25 Speak thou to Aaron and to his sons, This is the law of sacrifice for sin; it shall be offered before the Lord, in the place where burnt sacrifice is offered; it is holy of holy things. (Say thou to Aaron and his sons, This is the law for the sin offering; it shall be offered before the Lord, in the place where the burnt sacrifice is offered; it is a most holy, or sacred, thing.)

26 The priest that offereth it, shall eat it in the holy place, in the great porch of the tabernacle (in the courtyard of the Tabernacle).

27 Whatever thing shall touch the flesh thereof, shall be hallowed (shall be harmed by its holiness); if a cloak is besprinkled with the blood thereof, it shall be washed in the holy place.
