Psalms 141:3-5

Set a guard, O LORD, over my mouth; Keep watch over the door of my lips. Do not incline my heart to any evil thing, To practice deeds of wickedness With men who do iniquity; And do not let me eat of their delicacies. Let the righteous smite me in kindness and reprove me; It is oil upon the head; Do not let my head refuse it, For still my prayer is against their wicked deeds.
