'Splinter' in the Bible

And why do you look at the splinter in your brother's eye, and not notice the beam which is in your own eye?

Or how say to your brother, 'Allow me to take the splinter out of your eye,' while the beam is in your own eye?

Hypocrite, first take the beam out of your own eye, and then you will see clearly how to remove the splinter from your brother's eye.
