Leviticus 11:44-47

44For I am the Lord your God. You shall therefore consecrate yourselves, and you shall be holy; for I am holy. Neither shall you defile yourselves with any creeping thing that creeps on the earth.

45For I am the Lord who brings you up out of the land of Egypt, to be your God. You shall therefore be holy, for I am holy.

46‘This is the law of the animals and the birds and every living creature that moves in the waters, and of every creature that creeps on the earth,

47to distinguish between the unclean and the clean, and between the animal that may be eaten and the animal that may not be eaten.’ ”
