John Gill Commentary Matthew 7:4

"Or how wilt thou say to thy brother, Let me cast out the mote out of thine eye; and lo, the beam is in thine own eye?" — Matthew 7:4 (ASV)

Or how will you say to your brother? This is not so much an interrogation, as an expression of admiration, at the front and impudence of such censorious remarkers, and rigid observators; who not content to point at the faults of others, take upon them to reprove them in a very magisterial way: and it is as if Christ had said, with what face can you say to your friend or neighbour, let me pull out the mote out of your eye? give me leave to rebuke you sharply for your sin, as it deserves, and behold a beam is in your own eye; you are guilty of a far greater iniquity: astonishing impudence! Are you so blind, as not to see and observe your viler wickedness? Or which, if conscious of, how can you prevail upon yourself to take upon yourself to reprove and censure others?

Do you think your brother cannot see your beam? And may he not justly retort your iniquities upon you, which exceed his? and then what success can you promise yourself? Such persons are very unfit to be reprovers of others.
