Israel said: “Send Your light and Your truth; they will guide me” (Psalms 43:3). Great is the light of the Holy One blessed be He. The sun and the moon illuminate the world. From where do they illuminate?
It is from the sparks of the supernal light that they take, as it is stated: “By the light of Your arrows they will go, by the glow of the flash of Your spear” (Habakkuk 3:11). Great is the supernal light, as only one one-hundredth of it was given to humanity, as it is stated: “He knows what [ma]5The word ma is being read like mea which means one hundred. See Rashi Menahot 43b. is in the darkness” (Daniel 2:22).
That is why I crafted the sun and the moon, so they will illuminate before you, as it is stated: “God set them in the firmament of the heavens to illuminate” (Genesis 1:17). “Toward the front of the candelabrum, the seven lamps shall illuminate” – David said: “Life is in the light of the king's countenance” (Proverbs 16:15). Rabbi Yaakov ben Rabbi Yosei said: Joy is withheld from the wicked and given to Israel, as the Holy One blessed be He compelled Himself to reside with flesh and blood, with a lamp. As He said to them: “Toward the front of the candelabrum, [the seven lamps] shall illuminate.”
