Leviticus 7:1

Likewise this [is] the law of the trespass [offering]
Or the various rites and rules to be observed at the offering of it: the persons for whom it was to be made are described in the two preceding chapters, ( Leviticus 5:1-6:30 ) both such that sinned through ignorance, and knowingly, and here the place and parts of the offering, and how to be disposed of, are declared:

it [is] most holy;
wholly devoted for sacred use, either to the Lord, or to his priests; there were some things the Jews call light holy things, and others most holy in the highest degree, of this sort was the trespass offering.
