Do not defile yourselves by any crawling creature; do not become unclean or defiled by them.

Genesis 1:20
And God said, "Let the waters teem with living creatures, and let birds fly above the earth in the open expanse of the sky."

Genesis 7:21
And every living thing that moved upon the earth perished--birds, livestock, animals, every creature that swarms upon the earth, and all mankind.

Leviticus 11:42
Do not eat any creature that moves along the ground, whether it crawls on its belly or walks on four or more feet; for such creatures are detestable.

Leviticus 20:25
You are therefore to distinguish between clean and unclean animals and birds. Do not become contaminated by any animal or bird, or by anything that crawls on the ground; I have set these apart as unclean for you.

You shall not make yourselves abominable with any creeping thing that creeps, neither shall you make yourselves unclean with them, that you should be defiled thereby.
