Leviticus 11:46

44For I am the LORD your God. Sanctify yourselves therefore, and be holy; for I am holy. You shall not defile yourselves with any kind of creeping thing that moves on the earth.

45For I am the LORD who brought 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 animal, and of the bird, and of every living creature that moves in the waters, and of every creature that creeps on the earth,

47to make a distinction between the unclean and the clean, and between the living thing that may be eaten and the living thing that may not be eaten.’”
