Do not lie to one another, since you have taken off the old self with its practices. Colossians 3:9

“But now, you must put aside all such things as these: anger, rage, malice, slander, and filthy language from your mouth. Therefore, get rid of all moral filth and every expression of evil, and humbly receive the word planted in you, which can save your souls. And each of you must put off falsehood and speak truthfully to his neighbor, for we are members of one another.”
