Isaiah 52:11

Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you,

Remove out of the midst of Babylon, and go forth out of the land of the Chaldeans, and be as the he goats before the flocks.

But Peter said, Not so, Lord; for I have never eaten any thing that is common or unclean.

Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.

For I am the LORD that bringeth you up out of the land of Egypt, to be your God: ye shall therefore be holy, for I am holy.
