Pseudo Jonathan Genesis 1:26
25 God made the beasts of the earth according to their kind, kinds that are clean and kinds that are not clean, and the cattle according to their kind, and all the creeping things of the earth according to their kinds, kinds that are clean and kinds that are not clean. And God saw that it was good. 26 And God said to the angels who minister before him, who were created on the second day of the creation of the world, 'Let us make man in our image, in our likeness, and let them have dominion over the fish of the sea, and over the birds that are in the air of the heavens, and over the cattle, and over all the earth, and over every creeping thing that creeps upon the earth.' 27 And God created Adam in his own likeness, in the image of God he created him, with two hundred and forty-eight members, with six hundred and sixty-five nerves, and he formed a skin over him, and filled it with flesh and blood; male and female in their appearance he created them.
Pirkei DeRabbi Eliezer 4:1
THE CREATION ON THE SECOND DAY ON the second day the Holy One, blessed be He, created the firmament, the angels, fire for flesh and blood, and the fire of Gehinnom. Were not heaven and earth created on the first day, as it is said, "In the beginning God created the heaven and the earth" (Gen. 1:1)? Which firmament was created on the second day? Rabbi Eliezer said: || It was the firmament which is above the heads of the four Chajjôth (living creatures), (as it is said), "And over the head of the Chajjôth there was the likeness of a firmament, like the colour of the terrible crystal" (Ezek. 1:22). What is the meaning of (the expression), "like the colour of the terrible crystal"? It means like precious stones and pearls; it illuminates all the heavens like a lamp which is illuminating the whole house and like the sun which is shining with maximum intensity at noonday, as it is said, "The light dwelleth with him" (Dan. 2:22); and like this in the future will the righteous shed light, as it is said, "And they that be wise shall shine as the brightness of the firmament" (Dan. 12:3). Were it not for that firmament the world would be engulfed by the waters above it and below it; but (the firmament) divides the waters (above) from the waters (below), as it is said, "And God said, Let there be a firmament in the midst of the waters, (and let it divide the waters from the waters)" (Gen. 1:6), it illuminates between the waters above and the waters below.
Notes and References
"... Some ancient interpreters pointed specifically to the first day as the time of the angels' creation. Perhaps they did so because of the mention of the 'spirit of God' in Genesis 1:2, since 'spirit' was one term commonly understood to refer to angels ... Other sources saw the second day as the time of the angels' creation (because that was the day when the 'firmament' - deemed to be part of heaven, where the angels lived—was created) ..."
