Luke 6:41-42

41Perhaps you want to tell a friend about his little mistake. If you want to tell him, first remember your own bigger mistakes.

42If you do not do that, you will be like a person who has a big piece of wood in his eye. But then he says to his friend, “My friend, you have a little piece of dirt in your eye. Let me take it out for you.” Do not be like that person. You think you are better than your friend. But you are not. First, you must take the big piece of wood out of your eye. After that, your eyes will be clear and you will see well. Then you can take the small piece of dirt out of your friend's eye.’
