“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.
“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.
“For every firstborn among Bnei-Yisrael is Mine, whether human or animal. On the day I struck down the firstborn of the land of Egypt, I sanctified them for Myself.
At that time Adonai set the tribe of Levi apart to carry the Ark of the Covenant of Adonai, to stand before Adonai to serve Him and to pronounce blessings in His Name—as is the case to this day.
