Leviticus 1:16
And he shall pluck away his crop with his feathers, and cast it beside the altar on the east part, by the place of the ashes:
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.
