Мидраш к Брахо́т 8:10

At twilight on Saturday (evening), Adam was meditating in his heart and saying: Perhaps the serpent, which deceived me, will come in the evening, and he will bruise me in the heel. A pillar of fire was sent to him to give illumination about him and to guard him from all evil. Adam saw the pillar of fire and rejoiced in his heart, and he put forth his hands to the light of the fire, and said: Blessed art Thou, O Lord our God, King of the universe, who creates the flames of fire. And when he removed his hands from the light of the fire, he said: Now I know that the holy day has been separated from the work day here below (on earth), for fire may not be kindled on the Sabbath day; and in that hour he said: Blessed art Thou, O Lord our God, King of the universe, who divides || the holy from the profane, the light from the darkness.

Rabbi Mana said: How must a man say the Habdalah blessing? (He does this) over the cup of wine, with the light of fire, and he says: Blessed art Thou, O Lord our God, King of the universe, who creates the various flames of fire; and when he removes his hand from the fire (flame) he says: Blessed art Thou, O Lord, who divides the holy from the profane.
