"Judge Not"

"Judge not, that you be not judged. For with the judgment that you pronounce you will be judged, and the measure you give will be the measure you get. Why do you see the speck that is in your brother's eye, but do not notice the log that is in your own eye? Or how can you say to your brother, "Let me take the speck out of your eye," when there is the log in your own eye? You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your brother's eye." (Matthew 7:1-5)

These verses have puzzled me, especially in the context of the verses that follow.

"Do not give what is holy to dogs, and do not throw your pearls before swine" (Matthew 7:6)

"Beware of false prophets...You will know them by their fruits" (Matthew 7:15,16,20).

Thus, this principle isn't a statement of moral tolerance or a recognition of human faliability, so far as I can tell. To the contrary, my reading of the full context is that we must judge and indeed much of ethics is nothing more than judgment-- discerning of moral truth from falsehood. Thus, I would paraphase the phrase as "Judge not falsely, that you be not judged falsely."
