Ephesians 4:29-31

Let no harmful language come from your mouth, only good words that are helpful in meeting the need, words that will benefit those who hear them.

Don’t cause grief to God’s Ruach HaKodesh, for he has stamped you as his property until the day of final redemption.

Get rid of all bitterness, rage, anger, violent assertiveness and slander, along with all spitefulness.
