Exodus 29:29 BBE

²⁷  So you are to make holy the breast of the sheep which is waved and the leg which is lifted up on high, that is, of the sheep which is offered for Aaron and his sons;

²⁸  And it will be their part as a right for ever from the children of Israel, it is a special offering from the children of Israel, made from their peace-offerings, a special offering lifted up to the Lord.

²⁹  And Aaron's holy robes will be used by his sons after him; they will put them on when they are made priests.

³⁰  For seven days the son who becomes priest in his place will put them on when he comes into the Tent of meeting to do the work of the holy place.

³¹  Then take the sheep of the wave offering and let its flesh be cooked in water in a holy place.
