Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary
At the command of God, Moses received them to apply them to the purposes of the tabernacle, and handed them over to the Levites, "to every one according to the measure of his service," i.e., to the different classes of Levites, according to the requirements of their respective duties.
Jamieson-Fausset-Brown Bible Commentary
The Lord spake unto Moses, saying, Take it of them, that they may be to do the service of the tabernacle of the congregation--They exhibited a beautiful example to all who are great in dignity and in wealth, to be foremost in contributing to the support and in promoting the interests of religion. The strictness of the injunctions Moses had received to adhere with scrupulous fidelity to the divine model of the tabernacle probably led him to doubt whether he was at liberty to act in this matter without orders. God, however, relieved him by declaring His acceptance of the freewill offerings, as well as by giving instructions as to the mode of their distribution among the Levites. It is probable that in doing so, He merely sanctioned the object for which they were offered, and that the practical wisdom of the offerers had previously determined that they should be distributed "unto the Levites, to every man according to his service"--that is, more or fewer were assigned to each of the Levitical divisions, as their department of duty seemed to require. This divine sanction it is of great importance to notice, as establishing the principle, that while in the great matters of divine worship and church government we are to adhere faithfully to the revealed rule of faith and duty, minor arrangements respecting them may be lawfully made, according to the means and convenience of God's people in different places. "There is a great deal left to human regulation--appendages of undoubted convenience, and which it were as absurd to resist on the ground that an express warrant cannot be produced for them, as to protest against the convening of the people to divine service, because there is no Scripture for the erection and ringing of a church bell" [CHALMERS].
John Gill Bible Commentary
And the Lord spake unto Moses,.... Out of the tabernacle, before which the wagons and oxen were brought:
saying: as follows.
