Leviticus 7:30

“His own hands shall bring the offerings of the Lord made by fire, etc.] That is, such parts of the peace offerings as were to be burnt with fire, as the fat on several parts described in (<030303>Leviticus 3:3,4) the owners of the offerings were to bring them in the manner as will be presently observed: the fat with the breast, it shall he bring; the fat to be burnt, and the breast for the priest and his sons, as in the following verse (<030731>Leviticus 7:31): that the breast may be waved [for] a wave offering before the Lord; how this waving was performed, (see Gill on “<022924>Exodus 29:24”) particularly with respect to these peace offerings it was thus; if a thank offering, the priest…”
