“See, I have personally taken your kinsmen, the Levites, from among Bnei-Yisrael as a gift for you and your sons with you, dedicated to Adonai to serve in the work of the Tent of Meeting.
Now I am about to bring the flood—water upon the land—to destroy all flesh in which is the spirit of life from under the sky. Everything that is on the land will perish.
Then I, behold, I will harden the hearts of the Egyptians, and they will go in after them, so that I will be glorified over Pharaoh and all his army, his chariots and his horsemen.
Also look, I Myself have appointed with him Oholiab son of Ahisamach, of the tribe of Dan. Within the hearts of all who are wise-hearted I have placed skill, so that they may make everything that I have commanded you:
because all the firstborn are Mine. In the day when I was striking down all the firstborn in the land of Egypt, I consecrated to Myself every firstborn in Israel—whether man or animal—as Mine. I am Adonai.”
“Take the Levites in place of all the firstborn of Bnei-Yisrael, and the livestock of the Levites in place of their livestock. The Levites will be Mine. I am Adonai.
