APPOINTMENT TO THE PRIESTHOOD. (Exo. 28:1-43) take thou unto thee Aaron thy brother, and his sons with him--Moses had hitherto discharged the priestly functions (Psa 99:6), and he evinced the piety as well as humility of his character, in readily complying with the command to invest his brother with the sacred office, though it involved the perpetual exclusion of his own family. The appointment was a special act of God's sovereignty, so that there could be no ground for popular umbrage by the selection of Aaron's family, with whom the office was inalienably established and continued in unbroken succession till the introduction of the Christian era.
