6 Conceited people can never become wise, but intelligent people learn easily.

8 Why is a clever person wise? Because he knows what to do. Why is a stupid person foolish? Because he only thinks he knows.

15 A fool will believe anything; smart people watch their step.

1 “Do not judge others, so that God will not judge you, 2 for God will judge you in the same way you judge others, and he will apply to you the same rules you apply to others. 3 Why, then, do you look at the speck in your brother's eye and pay no attention to the log in your own eye? 4 How dare you say to your brother, ‘Please, let me take that speck out of your eye,’ when you have a log in your own eye? 5 You hypocrite! First take the log out of your own eye, and then you will be able to see clearly to take the speck out of your brother's eye.
