Numbers 1
AND the Lord spake unto Moses in the wilderness of Sinai, in the tabernacle of the congregation, on the first day of the second month, in the second year after they were come out of the land of Egypt, saying, Take ye the sum of all the congregation of the children of Israel, after their families, by the house of their fathers, with the number of their names, every male by their polls; from twenty years old and upward, all that are able to go forth to war in Israel: thou and Aaron shall number them by their armies.
And Moses and Aaron assembled all the congregation together on the first day of the second month. And as the Lord commanded Moses, so he numbered them in the wilderness of Sinai, every male from twenty years old and upward, all that were able to go forth to war. All they that were numbered were six hundred thousand and three thousand and five hundred and fifty.
But the Levites after the tribe of their fathers were not numbered among them. For the Lord had spoken unto Moses, saying, Only thou shalt not number the tribe of Levi, neither take the sum of them among the children of Israel: but thou shalt appoint the Levites over the tabernacle of testimony, and over all the vessels thereof, and over all things that belong to it: they shall bear the tabernacle, and all the vessels thereof; and they shall minister unto it, and shall encamp round about the tabernacle.
And the Lord spake unto Moses, saying, Bring the tribe of Levi near, and present them before Aaron the priest, that they may minister unto him. And thou shalt give the Levites unto Aaron and to his sons: they are wholly given unto him out of the children of Israel. And thou shalt appoint Aaron and his sons, and they shall wait on their priest's office: and the stranger that cometh nigh shall be put to death.
And the Lord spake unto Moses, saying, And I, behold, I have taken the Levites from among the children of Israel instead of all the firstborn among the children of Israel: therefore the Levites shall be mine; because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast: mine shall they be: I am the Lord.
And the Lord spake unto Moses in the wilderness of Sinai, saying, Number the children of Levi after the house of their fathers, by their families: every male from a month old and upward shalt thou number them. And Moses numbered them according to the word of the Lord, as he was commanded.
And the Lord spake unto Moses, saying, Speak unto Aaron and unto his sons, saying, On this wise ye shall bless the children of Israel, saying unto them, The Lord bless thee, and keep thee: the Lord make his face shine upon thee, and be gracious unto thee: the Lord lift up his countenance upon thee, and give thee peace. And they shall put my name upon the children of Israel; and I will bless them.
