'Cursed is he who sets light by his father or his mother.' All the people shall say, 'Amen.'
But I tell you, that everyone who is angry with his brother without a cause shall be in danger of the judgment; and whoever shall say to his brother, 'Raca!' shall be in danger of the council; and whoever shall say, 'You fool!' shall be in danger of the fire of Gehenna.
A fool shows his annoyance the same day, but one who overlooks an insult is prudent.
1 Samuel 25:14
But one of the young men told Abigail, Nabal's wife, saying, "Behold, David sent messengers out of the wilderness to Greet our master; and he railed at them.
Those who stood by said, "Do you malign God's high priest?"
One of the lawyers answered him, "Teacher, in saying this you insult us also."
Therefore prophesy concerning the land of Israel, and tell the mountains and to the hills, to the watercourses and to the valleys, Thus says the Lord Yahweh: Behold, I have spoken in my jealousy and in my wrath, because you have borne the shame of the nations:
therefore thus says the Lord Yahweh: I have sworn, [saying], Surely the nations that are around you, they shall bear their shame.
neither will I let you hear any more the shame of the nations, neither shall you bear the reproach of the peoples any more, neither shall you cause your nation to stumble any more, says the Lord Yahweh.
