Psalm 141:3-5

International Standard Version

³ Lord, set a guard over my mouth;
    keep watch over the door to my lips.
⁴ Don’t let my heart turn toward evil
    or involve itself in wicked activities
with men who practice iniquity.
    Let me not feast on their delicacies.

⁵ Let one who is righteous strike me;
    It is an act of gracious love.
Let him rebuke me,
    because it is oil for my head;
    do not let my head refuse it.
My prayers continuously will be
    against their wicked activities.
