A.T. Robertson Commentary Matthew 7:5

"Thou hypocrite, cast out first the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother`s eye." — Matthew 7:5 (ASV)

Shalt thou see clearly (διαβλεψεις). Only here and Lu 6:42 and Mr 8:25 in the New Testament. Look through, penetrate in contrast to βλεπεις, to gaze at, in verse 3. Get the log out of your eye and you will see clearly how to help the brother get the splinter out (εκβαλειν) of his eye.
