'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.

"And why look at the splinter in your brother's eye instead of giving careful attention to the beam in your own?

How can you say to your brother, 'Brother, let me take that splinter out of your eye,' when all the while you yourself do not see the beam in your own eye? Vain pretender! take the beam out of your own eye first, and then you will see clearly to take the splinter out of your brother's eye.

Because of the surpassing greatness and extraordinary nature of the revelations [which I received from God], for this reason, to keep me from thinking of myself as important, a thorn in the flesh was given to me, a messenger of Satan, to torment and harass me—to keep me from exalting myself!
