Luke 6:39-42

And He also spoke a parable to them: “A blind man cannot guide a blind man, can he? Will they not both fall into a pit? A pupil is not above his teacher; but everyone, after he has been fully trained, will be like his teacher. Why do you look at the speck that is in your brother’s eye, but do not notice the log that is in your own eye? Or how can you say to your brother, ‘Brother, let me take out the speck that is in your eye,’ when you yourself do not see the log that is in your own eye? You hypocrite, first take the log out of your own eye, and then you will see clearly to take out the speck that is in your brother’s eye.
