“So Aaron and his sonnes did all things which the Lord commanded by the hand of Moses.”
1611 King James Version (KJV)
8:36 So Aaron and his sons did all things - And thus the covenant of life and peace, #Mal 2:5|, was made with them. But after all the ceremonies used in their consecration, one point was reserved for the honour of Christ's priesthood. They were made priests without an oath; but Christ with an oath, #Heb 7:21|. For neither these priests, nor their priesthood was to continue. But His is a perpetual and unchangeable priesthood.
