'Unclean' in the Bible

“But whenever you want, you may slaughter and eat meat within any of your gates, according to the blessing the Lord your God has given you. Those who are clean or unclean may eat it, as they would a gazelle or deer,

Indeed, you may eat it as the gazelle and deer are eaten; both the clean and the unclean may eat it.

But among the ones that chew the cud or have divided hooves, you are not to eat these:the camel, the hare, and the hyrax,though they chew the cud, they do not have hooves—they are unclean for you;

and the pig, though it has hooves, it does not chew the cud—it is unclean for you.You must not eat their meat or touch their carcasses.

but you may not eat anything that does not have fins and scales—it is unclean for you.

All winged insects are unclean for you; they may not be eaten.

Eat it within your gates; both the unclean person and the clean may eat it, as though it were a gazelle or deer.

If there is a man among you who is unclean because of a bodily emission during the night, he must go outside the camp; he may not come anywhere inside the camp.

I have not eaten any of it while in mourning, or removed any of it while unclean, or offered any of it for the dead. I have obeyed the Lord my God; I have done all You commanded me.
