Judge not, that ye may not be judged;
for with what judgment ye judge, ye shall be judged; and with what measure ye mete, it shall be measured to you.
But why lookest thou on the mote that is in the eye of thy brother, but observest not the beam that is in thine eye?
Or how wilt thou say to thy brother, Allow [me], I will cast out the mote from thine eye; and behold, the beam is in thine eye?
Hypocrite, cast out first the beam out of thine eye, and then thou wilt see clearly to cast out the mote out of the eye of thy brother.
Give not that which is holy to the dogs, nor cast your pearls before the swine, lest they trample them with their feet, and turning round rend you.
