Charles Spurgeon Commentary Luke 11:24-26

"The unclean spirit when he is gone out of the man, passeth through waterless places, seeking rest, and finding none, he saith, I will turn back unto my house whence I came out. And when he is come, he findeth it swept and garnished. Then goeth he, and taketh [to him] seven other spirits more evil than himself; and they enter in and dwell there: and the last state of that man becometh worse than the first." — Luke 11:24-26 (ASV)

Whence I came out. And when he cometh, he findeth it swept and garnished.

The man has become quite a decent sort of fellow. He has given up his bad ways, and is a respectable member of society. The house is swept and garnished, but it is the devil's house all the same.
