Look, I myself have chosen your brothers the Levites from the Israelites as my gift to you, dedicated to the Lord to do the work that relates to the Tent of Meeting.
“You are to take the Levites in place of all the firstborn children of Israel, and the livestock of the Levites in place of their livestock, because the Levites belong to me. I am the Lord.
I have also chosen Oholiab, son of Ahisamach, from the tribe of Dan, to help him. I have also given all the craftsmen the skills needed to make everything that I have ordered you to make:
I will give the Egyptians a stubborn, hard-hearted attitude so that they will chase in after them. Then I will gain respect through what happens to Pharaoh and all his army, chariots, and horsemen.
because all the firstborn are mine. When I killed every firstborn in Egypt I set apart as holy to me all the firstborn of Israel, human and animal. They are mine. I am the Lord.”
