Deuteronomy 14:13

“You shall take with you of every clean animal by sevens, a male and his female; and of the animals that are not clean, two, a male and his female;

“Speak to the sons of Israel, saying, ‘These are the creatures which you may eat from all the animals that are on the earth.

‘These, moreover, you shall detest among the birds; they shall not be eaten; they are detestable: the eagle and the vulture and the buzzard,

‘You are therefore to separate between the clean animal and the unclean, and between the unclean bird and the clean; and you shall not make yourselves detestable by animal or by bird or by anything that creeps on the ground, which I have separated for you as unclean.

The owl will make its nest and find its escape there, And it will hatch its eggs and gather them in its shade. Surely, the falcons will be gathered there, Every one with its kind.

But Peter said, “By no means, Lord, for I have never eaten anything defiled and unclean.”
