Genesis 1:6
6 God said, “Let there be an expanse in the midst of the waters and let it separate water from water.” 7 So God made the expanse and separated the water under the expanse from the water above it. It was so. 8 God called the expanse “sky.” There was evening, and there was morning, a second day. 9 God said, “Let the water under the sky be gathered to one place and let dry ground appear.” It was so. 10 God called the dry ground “land” and the gathered waters he called “seas.” God saw that it was good.
Leviticus 11:2
2 “Tell the Israelites: ‘This is the kind of creature you may eat from among all the animals that are on the land. 3 You may eat any among the animals that has a divided hoof (the hooves are completely split in two) and that also chews the cud. 4 However, you must not eat these from among those that chew the cud and have divided hooves: The camel is unclean to you because it chews the cud even though its hoof is not divided. 5 The rock badger is unclean to you because it chews the cud even though its hoof is not divided. 6 The hare is unclean to you because it chews the cud even though its hoof is not divided. 7 The pig is unclean to you because its hoof is divided (the hoof is completely split in two) , even though it does not chew the cud. 8 You must not eat from their meat, and you must not touch their carcasses; they are unclean to you. 9 “‘These you can eat from all creatures that are in the water: Any creatures in the water that have both fins and scales, whether in the seas or in the streams, you may eat. 10 But any creatures that do not have both fins and scales, whether in the seas or in the streams, from all the swarming things of the water and from all the living creatures that are in the water, are detestable to you. 11 Since they are detestable to you, you must not eat their meat, and their carcass you must detest. 12 Any creature in the water that does not have both fins and scales is detestable to you. 13 “‘These you are to detest from among the birds—they must not be eaten, because they are detestable: the griffon vulture, the bearded vulture, the black vulture,
Notes and References
"... In Genesis 1 three spheres of existence are formed. Each is progressively separated from the others by divine fiat. On day two, the waters are separated by the introduction of an “expanse” (1:6), later named “sky” (1:8). On day three the waters under the sky are gathered to one place to allow “dry ground” (1:9) to appear. This dry ground is named “land” (1:10). On days four to six these three spheres are populated with their respective avian, aquatic, and terrestrial denizens as well as the “swarming creatures” found in each (1:20–21). Leviticus 11 shares this same spatial conception. The chapter is divided along the same lines as Genesis 1, sequentially focusing on “the beasts that are upon the land” (11:2), “all that are in the waters” (11:9), and “the flying creatures” (11:13) that inhabit the sky. The reversal of order between Genesis 1 (sky, water, land) and Leviticus 11 (land, water, sky) is significant, as reversal of this kind is a frequently noted marker of allusion. Thus, reversal of this kind heightens the probability for a textual connection over and above mere commonality of expression ..."
