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 are workers of iniquity; and let me not eat of their dainties.

⁵Let the righteous smite me, it is kindness; and let him reprove me, it is an excellent oil which my head shall not refuse: for yet my prayer also is for them in their calamities.
