'Speck' in the Bible

Why do you look at the speck in your brother’s eye but don’t notice the log in your own eye?

Or how can you say to your brother, ‘Let me take the speck out of your eye,’ and look, there’s a log in your eye?

Hypocrite! First take the log out of your eye, and then you will see clearly to take the speck out of your brother’s eye.
