Verse 36. So Aaron and his sons did all things - And thus the covenant of life and peace, Mal. ii, 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. vii, 21. For neither these priests, nor their priesthood was to continue. But His is a perpetual and unchangeable priesthood.
