Luke 11:24

When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest; and finding none, he saith, I will return unto my house whence I came out.
22

But when a stronger than he shall come upon him, and overcome him, he taketh from him all his armour wherein he trusted, and divideth his spoils.

23

He that is not with me is against me: and he that gathereth not with me scattereth.

24

When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest; and finding none, he saith, I will return unto my house whence I came out.

25

And when he cometh, he findeth it swept and garnished.

26

Then goeth he, and taketh to him seven other spirits more wicked than himself; and they enter in, and dwell there: and the last state of that man is worse than the first.

Counter-Arguments

The strongest case that this verse does not belong in this theme.

Dietary Laws Still Binding

The verse in Luke 11:24 describes the behavior of an "unclean spirit" (a demonic entity), not "unclean food." The "dry places" and "house" are metaphorical for the spirit's state and its former host, respectively. There is no linguistic or contextual connection to dietary laws or food distinctions in this passage. The concept of "unclean" in this verse refers to spiritual impurity, not ritual or dietary impurity.
