'Impure' in the Bible

On the other hand, you may slaughter and eat meat as you please when the Lord your God blesses you in all your villages. Both the ritually pure and impure may eat it, whether it is a gazelle or an ibex.

Like you eat the gazelle or ibex, so you may eat these; the ritually impure and pure alike may eat them.

However, you may not eat the following animals among those that chew the cud or those that have divided hooves: the camel, the hare, and the rock badger. (Although they chew the cud, they do not have divided hooves and are therefore ritually impure to you).

Also the pig is ritually impure to you; though it has divided hooves, it does not chew the cud. You may not eat their meat or even touch their remains.

but whatever does not have fins and scales you may not eat; it is ritually impure to you.

and any winged thing on the ground are impure to you -- they may not be eaten.

You may eat it in your villages, whether you are ritually impure or clean, just as you would eat a gazelle or an ibex.

When you go out as an army against your enemies, guard yourselves against anything impure.

If there is someone among you who is impure because of some nocturnal emission, he must leave the camp; he may not reenter it immediately.

her first husband who divorced her is not permitted to remarry her after she has become ritually impure, for that is offensive to the Lord. You must not bring guilt on the land which the Lord your God is giving you as an inheritance.
