If you claim to be religious but don’t control your tongue, you are fooling yourself, and your religion is worthless. James 1:26

“He who guards his mouth protects his life, but the one who opens his lips invites his own ruin. Wherefore, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath. Keep your tongue from evil and your lips from deceitful speech. Set a guard, O Lord, over my mouth; keep watch at the door of my lips. I will watch my ways so that I will not sin with my tongue; I will guard my mouth with a muzzle as long as the wicked are present. Let my mouth be filled with thy praise and with thy honor all the day long.”
