(21) In the tabernacle of the congregation.--Heb., in the tent of meeting--i.e., the place where God met the earthly ruler of His people. (See Exodus 25:22.)

Before the testimony--i.e., in front of the Ark which contained "the Testimony," or "Two Tables." (See Note on Exodus 16:34.)

Aaron and his sons.--The priestly character of Aaron and his descendants, laid down in the next chapter, is here anticipated.

From evening to morning.--See the second Note on Exodus 27:20.

Verse 21. The tabernacle of the congregation. Rather, "the tent of meeting" - the tent where God would meet the earthly ruler of the people (Exodus 25:22), and give him commands and directions - not the place of meeting for the people themselves, who might in no case go beyond the entrance to the structure. The testimony - i,e., the ark which contained the "testimony," or two tables of stone written with the finger of God. Aaron and his sons. Compare Exodus 24:1. The intention to confer the priesthood on the descendants of Aaron, first openly revealed in the next chapter (vers. 1-43), is tacitly assumed from time to time in the earlier narrative. Shall order it from evening to morning. See the comment on ver. 20. It is difficult to assign these words any distinct meaning unless we accept the view, that the lamp burnt during the night only. It shall be a statute for ever. This expression is not at all common. In Exodus it occurs only here and in four other places. In Leviticus it is met with some six or seven times. The portions of the law thus characterised must be regarded as of special importance. (See the homiletics on this verse.)

27:20,21 The pure oil signified the gifts and graces of the Spirit, which all believers receive from Christ, the good Olive, and without which our light cannot shine before men. The priests were to light the lamps, and tend them. It is the work of ministers, by preaching and expounding the Scriptures, which are as a lamp, to enlighten the church, God's tabernacle upon earth. Blessed be God, this light is not now confined to the Jewish tabernacle, but is a light to lighten the gentiles, and for salvation unto the ends of the earth.In the tabernacle of the congregation,.... The reasons usually given for this name of the tabernacle are, either because the children of Israel gathered and met together here at certain times, or because here the Lord met with Moses, and his successors, as he had promised, Exodus 25:22, but neither of them will hold good; not the first, because the place where the candlestick was, and which Aaron and his sons are here said to order, was in the holy place, into which only the priests entered, and therefore could not be called the tabernacle of the congregation, from the people of Israel being gathered and assembling there; not the latter, because it was in the most holy place, where the Lord promised to meet with Moses, and commune with him, even from between the cherubim over the mercy seat there: indeed, at the door of the tabernacle of the congregation the children of Israel assembled, and there the Lord met them, and so the whole might be called from thence, and there seems to be no other reason for it, Exodus 29:42 and this place was

without the vail, which is before the testimony; that is, without the vail which divided between the holy and the most holy place, and which vail was before the ark, where the law or the testimony was put; for the candlestick was in that part of the tabernacle which was without the vail, or in the holy place: and here

Aaron and his sons shall order it from evening to morning before the Lord; that is, they were to take care that the lamps which went out might be lighted; and that they be kept clear and burning, they were to trim and snuff them, for which they had proper instruments provided for them, Exodus 25:37. This points at the word of God, which shines as a light in a dark place, and is a lamp to the feet, and a light to the path, and to the constant application of Gospel ministers in preaching it, in order to enlighten men in all ages unto the end of the world:

it shall be a statute for ever unto their generations, on the behalf of the children of Israel; on whom it was incumbent to provide oil for the lamps, as long as the tabernacle and temple service lasted; and figured out either the maintenance of Gospel ministers by the churches, or the grace and gifts of the Spirit, with which they are furnished by the head of the church, often signified by oil in Scripture.
