Leviticus 7:19 - Matthew Poole's English Annotations on the Holy Bible

The flesh, to wit, of the holy offering, of which he is here treating; and therefore the general word is to be so limited; for other flesh one might eat in this case, Deuteronomy 12:15,22. That toucheth any unclean thing, after its oblation; which might easily happen, as it was conveyed from the altar to the place where it was eaten; for it was not eaten in the holy place, as appears, because it was eaten by the priests, together with the offerers, who might not come thither. As for the flesh, i.e. the other flesh; that which shall not be polluted by any unclean touch. All that be clean, whether priests or offerers, or guests invited to the feast. See 1 Samuel 9:12, 1 Samuel 20:26. Both the flesh and the eaters of it must be clean.
