The third part of the sermon on the mount.
Judge not, that you may not be judged, 
For with what judgment you judge, you shall be judged: and with what measure you mete, it shall be measured to you again. 
And why seest thou the mote that is in thy brother's eye; and seest not the beam that is in thy own eye? 
Or how sayest thou to thy brother: Let me cast the mote out of thy eye; and behold a beam is in thy own eye? 
Thou hypocrite, cast out first the beam in thy own eye, and then shalt thou see to cast out the mote out of thy brother's eye.
