The sons of Amram: Aaron and Moses. Aaron, along with his descendants, was set apart to be consecrated as most holy forever, to burn incense before Adonai, to minister to Him, and to bless in His name forever.
But when he became strong, his heart grew so haughty that he acted corruptly. For he trespassed against Adonai his God by entering into the Temple of Adonai to burn incense upon the altar of incense.
just as Adonai had spoken to him by Moses’ hand, so that it would be as a reminder to Bnei-Yisrael that no one who was not a descendant of Aaron should burn incense before Adonai, and so no one would become like Korah and his following.
Also did I not choose them from all the tribes of Israel to be My kohanim, to officiate at My altar, to burn incense and to wear an ephod before Me? Did I not give to the house of your father all the fire offerings of Bnei-Yisrael?
