Leviticus 14:12 - Albert Barnes' Notes on the Bible

This trespass-offering, with its blood and the oil, must be regarded as the main feature in the ceremony: no alteration being permitted even in the case of the poor Leviticus 14:21-23. There appears to be no other case in which an entire victim was waved (see Leviticus 7:30) before Yahweh. The Levites are spoken of as “a wave offering,” Numbers 8:11-15 (see the margin). The man in this case, represented by his trespass-offering, was dedicated as a Wave-offering in like manner.
