28 and it shall be for Aaron and his sons as their portion forever from the children of Israel; for it is a wave offering: and it shall be a wave offering from the children of Israel of the sacrifices of their peace offerings, even their wave offering to Yahweh.
Matthew Henry's Commentary on Exodus 29:28
Commentary on Exodus 29:1-37
(Read Exodus 29:1-37)
Aaron and his sons were to be set apart for the priest's office, with ceremony and solemnity. Our Lord Jesus is the great High Priest of our profession, called of God to be so; anointed with the Spirit, whence he is called Messiah, the Christ; clothed with glory and beauty; sanctified by his own blood; made perfect, or consecrated through sufferings, Matthew 12:28,) and by him the merit of Christ is applied to our souls. This consecration signifies the admission of a sinner into the spiritual priesthood, to offer spiritual sacrifices, acceptable to God through Jesus Christ.
