Just Man

When he {Pilate} was set down on the judgement seat, his wife sent unto him, saying {NIV: sent him this message}, Have thou nothing to do with that just man: for I have suffered many things this day in a dream because of him. Matthew 27:19
Pontius Pilate, the Roman governor who condemned Jesus to death, received this message from his wife while Jesus was on trial.  She tried to get Pilate to release Jesus, because it had been revealed to her in a dream that He was innocent of the charges against Him.
Pilate also knew that Jesus was not guilty, but he caved in to political pressure from the Jewish religious leaders and pronounced the death penalty against Jesus.  Pilate washed his hands before the crowd and declared, “I am innocent of the blood of this just person” (Matthew 27:24).
The word just, as applied to Jesus by Pilate and his wife, means “innocent.”  But in other contexts in the New Testament, the names Just (Acts 3:14) Just One (Acts 7:52; 22:14), and Righteous Man (Luke 23:47) refer to Jesus’ righteousness and holiness.
Jesus, the Sinless and Righteous One, was not guilty of any crime or wrongdoing.  This makes His death on our behalf all the more meaningful.  He willingly laid down His life on the cross as the sacrifice for our sin.
