"JUDGE NOT, THAT YE BE NOT JUDGED."
I think the following text may be the most misquoted in the Bible. People quote the first sentence - the first seven words - leaving out the context. When read in its context we can see that it's a warning against hypocrisy. What it does not mean is 'never judge'. The idea of going through life never making judgments is absurd and the opposite of what the Bible requires.
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 THEY BROTHER'S EYE. (Matthew 7: 1-5).
