SEV Biblia, Chapter 7:34
porque he tomado de los hijos de Israel, de sus sacrificios de paz, el pecho de la mecedura, y la espaldilla de la apartadura, y lo he dado a Aarón el sacerdote y a sus hijos, por estatuto perpetuo de los hijos de Israel.
John Gill's Bible Commentary
Ver. 34. For the wave breast and the heave shoulder have I taken of the children of Israel , etc.] These two parts were particularly pitched upon and selected: from off the sacrifices of their peace offering ; the rest being allowed the owners, besides what were burnt: and have given them unto Aaron the priest and unto his sons, by a statute for ever from among the children of Israel ; as long as the priesthood lasted, even to the coming of the Messiah, in whom all these sacrifices would have their accomplishment and their end.
Matthew Henry Commentary
Verses 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' 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 from, in token of his regard to God as the Lord of the whole earth. Be persuaded an encouraged to feed and feast upon Christ, our Peace-offering. Thi 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 the 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' patience be run out, for eating the third day will not be accepted, no will catching at Christ when thou art gone to hell! (Le 7:35-38)
