20 You shall further command the Israelites to bring you pure oil of beaten olives for the light, so that a lamp may be set up to burn regularly. 21 In the tent of meeting, outside the curtain that is before the covenant, Aaron and his sons shall tend it from evening to morning before the Lord. It shall be a perpetual ordinance to be observed throughout their generations by the Israelites.
Matthew Henry's Commentary on Exodus 27:20-21
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.
