21 In the Tent of Meeting, the area outside the curtain that veils The Testimony, Aaron and his sons will keep this light burning from evening until morning before God. This is to be a permanent practice down through the generations for Israelites.

Matthew Henry's Commentary on Exodus 27:21

Commentary on Exodus 27:20-21

(Read Exodus 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.
