Thematic Bible: Aaron and his sons

And the Lord was angry with Moses, and said, Is there not Aaron, your brother, the Levite? To my knowledge he is good at talking. And now he is coming out to you: and when he sees you he will be glad in his heart. Let him give ear to your voice, and you will put my words in his mouth; and I will be with your mouth and with his, teaching you what you have to do. And he will do the talking for you to the people: he will be to you as a mouth and you will be to him as God.

Then let Aaron and his sons come to the door of the Tent of meeting; and after washing them with water, You are to put on Aaron the holy robes; and you are to put oil on him, and make him holy, so that he may be my priest. And take his sons with him and put coats on them; read more.
And put oil on them as you did on their father, so that they may be my priests: the putting on of oil will make them priests for ever, from generation to generation.
