Numbers 3:36-51

36 And the oversight -- the charge of the sons of Merari -- [is] the boards of the tabernacle, and its bars, and its pillars, and its sockets, and all its vessels, and all its service,
37 and the pillars of the court round about, and their sockets, and their pins, and their cords.
38 And those encamping before the tabernacle eastward, before the tent of meeting, at the east, [are] Moses and Aaron, and his sons, keeping the charge of the sanctuary for the charge of the sons of Israel, and the stranger who cometh near is put to death.
39 All those numbered of the Levites whom Moses numbered -- Aaron also -- by the command of Jehovah, by their families, every male from a son of a month and upward, [are] two and twenty thousand.
40 And Jehovah saith unto Moses, `Number every first-born male of the sons of Israel from a son of a month and upward, and take up the number of their names;
41 and thou hast taken the Levites for Me (I [am] Jehovah), instead of every first-born among the sons of Israel, and the cattle of the Levites instead of every firstling among the cattle of the sons of Israel.'
42 And Moses numbereth, as Jehovah hath commanded him, all the first-born among the sons of Israel.
43 And all the first-born -- male -- by the number of names, from a son of a month and upward, of their numbered ones, are two and twenty thousand two hundred and seventy and three.
44 And Jehovah speaketh unto Moses, saying,
45 `Take the Levites instead of every first-born among the sons of Israel, and the cattle of the Levites instead of their cattle; and the Levites have been Mine; I [am] Jehovah.
46 `And [from] those ransomed of the two hundred and seventy and three (who are more than the Levites) of the first-born of the sons of Israel,
47 thou hast even taken five shekels a-piece by the poll -- by the shekel of the sanctuary thou takest; twenty gerahs the shekel [is];
48 and thou hast given the money to Aaron, and to his sons, whereby those over and above are ransomed.'
49 And Moses taketh the ransom money from those over and above those ransomed by the Levites;
50 from the first-born of the sons of Israel he hath taken the money, a thousand and three hundred and sixty and five -- by the shekel of the sanctuary;
51 and Moses giveth the money of those ransomed to Aaron, and to his sons, according to the command of Jehovah, as Jehovah hath commanded Moses.
