Apocalypse of Abraham 12:1-8
1And we went, the two of us alone together, forty days and nights. And I ate no bread and drank no water, because (my) food was to see the angel who was
2with me, and his discourse with me was my drink. We came to God's mountain,
3glorious Horeb. And I said to the angel, "Singer of the Eternal One, behold I have no sacrifice with me, nor do I know a place for an altar on the mountain, so how
4shall I make the sacrifice?" And he said, "Look behind you." And I liked behind me. And behold all the prescribed sacrifices were following us: the calf,
5the she-goat, the ram, the turtledove, and the pigeon.
6"Abraham." And I said, "Here I am." And he said to me, "Slaughter all these
7and divide the animals exactly into halves. But do not cut the birds apart. And give them to the men whom I will show you standing beside you, for they are the
8altar on the mountain, to offer sacrifice to the Eternal One. The turtledove and the pigeon you will give to me for I will ascend on the wings of the birds to show you (what) is in the heavens, on the earth and in the sea, in the abyss, and in the lower depths, in the garden of Eden and in its rivers, in the fullness of the universe. And you will see its circles in all."
