"You must either make the tree healthy and its fruits healthy or make the tree sickly and its fruits sickly, for a tree is judged by its fruit.

You must recognize them by their fruits. People do not pick grapes from thornbushes or figs from thistles, do they?

So you must recognize them by their fruits.

But many who are first now will be last then, and many who are last now will be first then."

So those who are last now will be first then, and those first will be last."
