21 The lampstand will stand in the Tabernacle, in front of the inner curtain that shields the Ark of the Covenant. Aaron and his sons must keep the lamps burning in the Lord 's presence all night. This is a permanent law for the people of Israel, and it must be observed from generation to generation.
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.
