Judge Not . . .

Zechariah 8:16
These then are the things you must do: Speak the truth to one another; judge with honesty and complete justice in your gates.

John 12:48
Whoever rejects me and does not accept my words has something to judge him: the word that I spoke, it will condemn him on the last day.

Matthew 18:15-17
15  If your brother sins [against you], go and tell him his fault between you and him alone. If he listens to you, you have won over your brother. 
16   If he does not listen, take one or two others along with you, so that ‘every fact may be established on the testimony of two or three witnesses.
17  If he refuses to listen to them, tell the church. If he refuses to listen even to the church, then treat him as you would a Gentile or a tax collector.

Proverbs 31:9 
Open thy mouth, judge righteously, and plead the cause of the poor and needy.   

1 Corinthians 11:27-29
27  Therefore whoever eats the bread or drinks the cup of the Lord unworthily will have to answer for the body and blood of the Lord.
28  A person should examine himself,  and so eat the bread and drink the cup.  
29  For anyone who eats and drinks without discerning the body, eats and drinks judgment on himself. 

John 7:24
Do not judge according to appearance, but judge with righteous judgment.
