The eighth law revealed on this day was the lighting of the candlestick. After all the princes of the tribes had brought their gifts to the sanctuary, and God had bidden Moses to let them offer each his offering, one a day, throughout twelve days, Aaron, profoundly agitated, thought: "Woe is me! It seems as if, owing to my sin, my tribe has been excluded by God from participating in the dedication of the sanctuary."
Hereupon God said to Moses: "Go to Aaron and say to him, 'Do not fear that thou art slighted, and art deemed inferior to the other princes of the tribes. Thou, on the contrary, shalt enjoy a greater glory than all of these, for thou art to light the lamps of the candlestick in the sanctuary.'" When Israel heard God's command that the lights of the sanctuary be lighted, they said: "O Lord of the world!
Thou biddest us make a light for Thee that are the light of the world, and with whom light dwelleth." But God replied: "Not because I need your light do I bid you burn lamps before Me, but only the I might thereby distinguish you in the eyes of the nations that will say, 'Behold the people of Israel, that hold up a light before Him who bestoweth light upon the world.' By your own eye-sight can you see how little need I have of your light.
You have the white of the eye and the black of the eye, and it is by means of this dark part of the eye that you are enabled to see, and not through the light part of the white of the eye. How should I, that am all light, have need of your light!" God furthermore said: "A mortal of flesh and blood lights one light by means of another that is burning, I have brought forth light out of darkness: 'In the beginning darkness was upon the face of the deep,' whereupon I spake, 'Let there be light: and there was light.'
Shall I now be in need of your illumination? Nay, I commanded you to light the candles in the sanctuary that I might distinguish you and give you another opportunity of doing a pious deed, the execution of which I will reward in the future world by letting a great light shine before you; and, furthermore, if you will let the candles shine before Me in My sanctuary, I shall protect from all evil your spirit, 'the candle of the Lord.'"
