Exodus

There shall no stranger eat of the holy thing: a sojourner of the priest, or an hired servant, shall not eat of the holy thing.

That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:

Ye shall not eat of any thing that dieth of itself: thou shalt give it unto the stranger that is in thy gates, that he may eat it; or thou mayest sell it unto an alien: for thou art an holy people unto the Lord thy God. Thou shalt not seethe a kid in his mother’s milk.
