Matthew 8:28-32

And when he came to the other side, to the country of the Gadarenes, two demon-possessed men met him, coming out of the tombs, so fierce that no one could pass that way. And behold, they cried out, “What have you to do with us, O Son of God? Have you come here to torment us before the time?” Now a herd of many hogs was feeding at some distance from them. And the demons begged him, saying, “If you cast us out, send us away into the herd of hogs.” And he said to them, “Go.” So they came out and went into the hogs, and behold, the whole herd rushed down the steep bank into the sea and drowned in the waters.

Leviticus 11:7

And the hog, because it parts the hoof and is cloven-footed but does not chew the cud, is unclean to you.

Genesis 1:30

And to every beast of the earth and to every bird of the heavens and to everything that creeps on the earth, everything that has the breath of life, I have given every green plant for food.” And it was so.

Matthew 7:6

“Do not give dogs what is holy, and do not throw your pearls before hogs, lest they trample them underfoot and turn to attack you.
