 for the 22,000 Levites, and the cattle of the Levites were also set against the first-born of the cattle of the tribes of Israel, though without their being numbered and exchanged head for head. In Num 3:44 and Num 3:45 the command of God concerning the adoption of the Levites is repeated, for the purpose of adding the further instructions with regard to the 273, the number by which the first-born of the tribes exceeded those of the Levites. “And as for the redemption of the 273 (lit., the 273 to be redeemed) of the first-born of the children of Israel which were more than the Levites, thou shalt take five shekels a head,” etc. This was the general price established by the law for the redemption of the first-born of men (see Num 18:16). On the sacred shekel, see at Exo 30:13. The redemption money for 273 first-born, in all 1365 shekels, was to be paid to Aaron and his sons as compensation for the persons who properly belonged to Jehovah, and had been appointed as first-born for the service of the priests.

verses 49-51
“The redeemed of the Levites” are the 22,000 who were redeemed by means of the Levites. In Num 3:50, the Chethibh הפּדים is the correct reading, and the Keri הפּדים an unnecessary emendation. The number of the first-born and that of the Levites has already been noticed in the introduction to Numbers 1. =Chap. 4=

Verse 1
Rules of Service, and Numbering of the Levites Qualified for Service. - After the adoption of the Levites for service at the sanctuary, in the place of the first-born of Israel, Moses and Aaron mustered the three families of the Levites by the command of God for the service to be performed by those who were between the ages of 30 and 50. The particulars of the service are first of all described in detail (vv. 4-33); and then the men in each family are taken, of the specified age for service (vv. 34-49). The three families are not arranged according to the relative ages of their founders, but according to the importance or sacredness of their service. The Kohathites take the lead, because the holiest parts of the tabernacle were to be carried and kept by this family, which included the priests, Aaron and his sons. The service to be performed by each of the three Levitical families is introduced in every case by a command from God to take the sum of the men from 30 years old to 50 (see Num 4:1-3, Num 4:21-23, Num 4:29 and Num 4:30).
