Leviticus 11:8

Ye shall not touch — Not in order to eating, as may be gathered by comparing this with Genesis 3:3. But since the fat and skins of some of the forbidden creatures were useful, for medicinal and other good purposes, and were used by good men, it is not probable that God would have them cast away. Thus God forbad the making of images, Exodus 20:4, not universally, but in order to the worshipping them, as Christian interpreters agree.
