Deuteronomy 14:3

¹⁴Then I said, “Ah Lord GOD! Behold, my soul has not been polluted; for from my youth up even until now I have not eaten of that which dies of itself, or is torn of animals. No abominable meat has come into my mouth!”

²⁵“‘You shall therefore make a distinction between the clean animal and the unclean, and between the unclean fowl and the clean. You shall not make yourselves abominable by animal, or by bird, or by anything with which the ground teems, which I have separated from you as unclean for you.

⁴³You shall not make yourselves abominable with any creeping thing that creeps. You shall not make yourselves unclean with them, that you should be defiled by them.

¹⁴I know and am persuaded in the Lord Jesus that nothing is unclean of itself; except that to him who considers anything to be unclean, to him it is unclean.

¹²in which were all kinds of four-footed animals of the earth, wild animals, reptiles, and birds of the sky. ¹³A voice came to him, “Rise, Peter, kill and eat!”

¹⁴But Peter said, “Not so, Lord; for I have never eaten anything that is common or unclean.”

²⁸But if anyone says to you, “This was offered to idols,” don’t eat it for the sake of the one who told you, and for the sake of conscience. For “the earth is the Lord’s, with all its fullness.”

⁴who sit among the graves, and spend nights in secret places; who eat pig’s meat, and broth of abominable things is in their vessels;

¹⁵To the pure, all things are pure, but to those who are defiled and unbelieving, nothing is pure; but both their mind and their conscience are defiled.
