Psalms 141:3-5

³Set a watch, O Jehovah, before my mouth; Keep the door of my lips.

⁴Incline not my heart to any evil thing, To practise deeds of wickedness With men that work iniquity: And let me not eat of their dainties.

⁵Let the righteous smite me, it shall be a kindness; And let him reprove me, it shall be as oil upon the head; Let not my head refuse it: For even in their wickedness shall my prayer continue.
