Acts 24:20

So he said to them, “Yahweh is witness against you, and His anointed is witness this day that you have found nothing in my hand.” And they said, “He is witness.”

Then these men said, “We will not find any ground of accusation against this Daniel unless we find it against him with regard to the law of his God.”

“But I say to you that everyone who is angry with his brother shall be guilty before the court; and whoever says to his brother, ‘Raca,’ shall be guilty before the Sanhedrin; and whoever says, ‘You fool,’ shall be guilty enough to go into the fiery hell.
