Leviticus 11:44

For I am the Lord your God; consecrate yourselves, therefore, and be holy, because I am holy. You must not defile yourselves by any creature that crawls along the ground.

Note Here and in verse 45; cited in 1 Peter 1:16

For I am the Lord your God: ye shall therefore sanctify yourselves, and ye shall be holy; for I am holy: neither shall ye defile yourselves with any manner of creeping thing that creepeth upon the earth.

For 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.

For I am Jehovah your God: sanctify yourselves therefore, and be ye holy; for I am holy: neither shall ye defile yourselves with any manner of creeping thing that moveth upon the earth.
