And the priest shall burn the fat upon the altar,.... Of burnt offering, even the fat upon the inwards, the two kidneys, the flanks, the caul, and liver:

but the breast shall be Aaron's and his sons; which being waved before the Lord for a wave offering, was the Lord's, and so was given to his priests to eat of, for the service done by them, it being but reasonable that they that serve at the altar should live of it; and thus, with other things, a maintenance was provided for the priests and their families, as ought also to be for Gospel ministers under the present dispensation.

And the priest shall burn the fat upon the altar: but the breast shall be Aaron's and his sons'.

7:31 His sons - The portion of every succeeding high - priest and his family.

7:28-34 The priest who offered, was to have the breast and the right shoulder. When the sacrifice was killed, the offerer himself must present God's part of it; that he might signify his cheerfully giving it up to God. He was with his own hands to lift it up, in token of his regard to God as the God of heaven; and then to wave it to and fro, in token of his regard to God as the Lord of the whole earth. Be persuaded and encouraged to feed and feast upon Christ, our Peace-offering. This blessed Peace-offering is not for the priests only, for saints of the highest rank and greatest eminence, but for the common people also. Take heed of delay. Many think to repent and return to God when they are dying and dropping into hell; but they should eat the peace-offering, and eat it now. Stay not till the day of the Lord's patience be run out, for eating the third day will not be accepted, nor will catching at Christ when thou art gone to hell!
