Matthew 7
Judging others
Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. And why beholdest thou the mote that is in thy brother’s eye, but considerest not the beam that is in thine own eye? Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye? Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother’s eye.
Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.
Jesus warns against judging others, since the same standard will be applied to the one who judges. With a comic image he tells his hearers to remove the plank from their own eye before pointing out the speck in someone else's. He adds a puzzling saying about not giving holy things to dogs or pearls to pigs.
What does this mean?
A 'mote' (KJV) is a speck of dust; a 'beam' is a large wooden plank. 'Mete' means measure out. Street dogs (scavengers) and pigs (unclean under the Law) were insulting images.
Why does it matter?
The warning targets hypocritical condemnation; Matthew elsewhere expects discernment (7:15–20) and correction within the community (18:15–17). The meaning of verse 6 is uncertain. Some read it as advice not to press teaching on those who scorn it; an early Christian manual, the Didache, applied it to admitting only the baptised to the Lord's Supper.
