Leviticus 1:16

16 Soothly he shall cast forth the little bladder of the throat, or the crop, and the feathers beside the altar, at the east coast, in the place in the which the ashes be wont to be cast out; (And he shall throw away the crop of the throat, and the feathers, beside the altar, on the east side, in the place where the ashes be poured out;)

Leviticus 1:16 Meaning and Commentary

Leviticus 1:16

And he shall pluck away his crop with his feathers
Or "with its meat", or "dung", as Onkelos renders it, meaning that which was in its crop; and so the Jerusalem Targum interprets it, "with its dung"; and Jonathan's paraphrase is, "with its collection", or what was gathered together in the crop; it includes the entrails, as Gersom observes:

and cast it beside the altar on the east part, by the place of the
ashes;
where the ashes of the burnt offering were put every day, and every time such an offering was made; and all this answered to the washing of the inwards, and legs of the other burnt offerings, and signified the same thing, the cleanness and purity of Christ, and of his people by him.

Leviticus 1:16 In-Context

14 Forsooth if the offering of burnt sacrifice to the Lord is of birds, of turtles, or of culvers birds, (And if the offering to the Lord is a burnt sacrifice of birds, that is, of turtledoves, or of young pigeons,)

15 the priest shall offer it at the altar; and when the head is writhed to the neck, and the place of the wound is broken, he shall make the blood run down on the brink of the altar.

16 Soothly he shall cast forth the little bladder of the throat, or the crop, and the feathers beside the altar, at the east coast, in the place in the which the ashes be wont to be cast out; (And he shall throw away the crop of the throat, and the feathers, beside the altar, on the east side, in the place where the ashes be poured out;)

17 and the priest shall break the wings thereof, and he shall not carve it, neither part it with iron; and he shall burn it on the altar, when fire is put under the wood; it is a burnt sacrifice, and an offering of sweetest odour to the Lord. (and the priest shall break its wings, but he shall not carve it, or cut it, with anything made out of iron; and he shall burn it on the altar, when fire is put under the wood; yea, it is a burnt sacrifice, for an offering of the sweetest aroma to the Lord.)
