| Gill's Exposition of the Entire Bible Their brethren also the Levites,.... Who were not skilled in singing, and employed in that service, even the rest of the Kohathites, Gershonites, and Merarites: were appointed unto all manner of service of the tabernacle of the house of God; some were porters at the gates; others had the care of the vessels; others slew the beasts for sacrifices, flayed them, and cut them up, and brought the pieces to the altar of burnt offerings, for the priests to offer.
Keil and Delitzsch Biblical Commentary on the Old Testament(1 Chronicles 6:33-34). "And their brethren the Levites," i.e., the other Levites besides the singers just mentioned, "were נתוּנים given for every service of the dwelling of the house of God," i.e., given to Aaron and his sons (the priests) for the performance of service in the carrying on of the worship; cf. Numbers 3:9; Numbers 8:16-19; Numbers 18:6. But Aaron and his sons had three duties to perform: (1) they burnt the offerings on the altar of burnt-offering and on the altar of incense, cf. Numbers 18:1-7; (2) they looked after all the service of the holy place; (3) they had to atone for Israel by offering the atoning-sacrifices, and performing the cleansings according to all that Moses commanded. This last clause refers to all the three above-mentioned duties of the priests. Moses is called the servant of God, as in Deuteronomy 34:5; Joshua 1:1, Joshua 1:13.
Geneva Study BibleTheir {i} brethren also the Levites were {k} appointed unto all manner of service of the tabernacle of the house of God. (i) The Levites are called the singers brothers because they came from the same stock. (k) Read Nu 4:4.
Jamieson-Fausset-Brown Bible Commentary48. Their brethren also the Levites were appointed unto all manner of service-Those of them who were endowed with musical tastes and talents were employed in various other departments of the temple service.
Matthew Henry's Concise Commentary6:1-81 Genealogies. - We have an account of Levi in this chapter. The priests and Levites were more concerned than any other Israelites, to preserve their descent clear, and to be able to prove it; because all the honours and privileges of their office depended upon their descent. Now, the Spirit of God calls ministers to their work, without any limit as to the families they came from; and then, as now, though believers and ministers may be very useful to the church, none but our great High Priest can make atonement for sin, nor can any be accepted but through his atonement. |
