(Exodus, Ibid. 21) "And the L–rd went before them by day": We are hereby taught that as one metes it out to others, so is it meted out to him. Abraham accompanied the ministering angels, viz. (Genesis 18:16) "And Abraham went with them to escort them, and the L–rd accompanied his children in the desert for forty years, viz.: "And the L–rd went before them by day with a pillar of cloud." Of our father Abraham it is written (Genesis, Ibid. 5) "And I will take a piece of bread," and the Holy One Blessed be He brought down the manna for forty years, viz. (Exodus 16:4) "Behold, I shall rain down bread for you, etc." Of Abraham it is written (Genesis, Ibid.) "Let there be taken now a little water, etc.", and the Holy One Blessed be He raised for His children a well in the desert, viz. (Numbers 21:17) "Bring up, O well—sing to it." Of Abraham it is written (Genesis, Ibid. 7) "And to the herd Abraham ran," and the Holy One Blessed be He flew in quail for his children, as it is written (Numbers 11:31) "And a wind went forth from the land and flew in quail from the sea." Of Abraham it is written (Genesis, Ibid. 4) "And recline under the tree," and the Holy One Blessed be He spread out for his children seven clouds of glory," as it is written (Psalms 105:39) "He spread out a cloud for shelter and a fire to illumine the night." Of Abraham it is written (Genesis, Ibid. 8) "and he stood over them," and the Holy One Blessed be He defended his children in Egypt, that they not be smitten, viz. (Exodus 12:23) "and the L–rd will skip over the door, etc."
