Don’t be like a horse or a mule. They can’t understand anything. They have to be controlled by bits and bridles. If they aren’t, they won’t come to you.
If you whip a person who makes fun of others, childish people will learn to be wise. If you warn those who already understand what is right, they will gain even more knowledge.
Suppose you could grind a foolish person in a mill. Suppose you could grind them as you would grind grain with a tool. Even then you could not remove their foolishness from them.
I already warned you during my second visit. I now say it again while I’m away. When I return, I won’t spare those who sinned earlier. I won’t spare any of the others either.
