Psalm 141:3-5

Set a guard, O LORD, over my mouth; keep watch over the door of my lips! Do not let my heart incline to any evil, to busy myself with wicked deeds in company with men who work iniquity, and let me not eat of their delicacies! Let a righteous man strike me—it is a kindness; let him rebuke me—it is oil for my head; let my head not refuse it. Yet my prayer is continually against their evil deeds.
