Jesus's Reference to the Son of Man in the Book of Revelation

In matthew 24, jesus says that the son of man will come and weed out everything that causes sin. He also makes a reference to this in capernaum where he is just starting a superpopular healing mission. And it comes in conjunction with his imagery about this sifting or sorting out. It was a reference back, maybe most observably, to daniel, chapter seven. Daniel has this vision, and the vision involves something that is like a son of man, according to daniel. But what i really want to draw your attention to is that language, but the son ofMan, has no place to lay his head. That's not a meaningless throw away phrase
