New King James Version (NKJV)
Numbers 3
47 you shall take five shekels for each one individually; you shall take them in the currency of the shekel of the sanctuary, the shekel of twenty gerahs.
48 And you shall give the money, with which the excess number of them is redeemed, to Aaron and his sons."
49 So Moses took the redemption money from those who were over and above those who were redeemed by the Levites.
50 From the firstborn of the children of Israel he took the money, one thousand three hundred and sixty-five shekels, according to the shekel of the sanctuary.
51 And Moses gave their redemption money to Aaron and his sons, according to the word of the Lord, as the Lord commanded Moses.
Numbers 4
1 Then the Lord spoke to Moses and Aaron, saying:
2 "Take a census of the sons of Kohath from among the children of Levi, by their families, by their fathers’ house,
3 from thirty years old and above, even to fifty years old, all who enter the service to do the work in the tabernacle of meeting.
4 "This is the service of the sons of Kohath in the tabernacle of meeting, relating to the most holy things:
5 When the camp prepares to journey, Aaron and his sons shall come, and they shall take down the covering veil and cover the ark of the Testimony with it.
6 Then they shall put on it a covering of badger skins, and spread over that a cloth entirely of blue; and they shall insert its poles.
