Matthew 7:1-3King James Version (KJV)7 Judge not, that ye be not judged.
2 For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.
3 And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?
Another time, Jesus gave a concrete example to a crowd of self-righteous men, sure about their positions, and arrogant in their knowledge of what the rules of their culture demanded, intending to show up this up-start minor "politician" Jesus, and about to administer summary judgment and execution themselves to a sinner. asked Jesus how they should handle the "case." (I'm not trying to equate Ted Cruz with Jesus, but the cases are amazingly parallel.)
In John 8:1 - 11 scribes and Pharisees had caught a woman in the act of adultery (the woman commonly referred to as the prostitute) and told Jesus who was teaching in the temple that the Mosaic Law required she be stoned to death. Trying to make an opportunity of this to trick Jesus that they might accuse Him, they, with stones in hand, asked Jesus what He says about the Law. After Jesus tried to ignore their repeated questioning, He told them "He that is without sin among you, let him first cast a stone at her." One by one each man dropped his stone and walked away.
The situation was a set up. Roman law would allow him to be charged with murder if he killed someone without the Roman government ordering it done. It was a lot about pointing outright intent. He strongly told the woman to “sin no more”.
