Psalms 141:3-6

3Lord, set up a guard for my mouth; keep watch at the door of my lips.

4Do not let my heart turn to any evil thing or perform wicked acts with evildoers. Do not let me feast on their delicacies.

5Let the righteous one strike me — it is an act of faithful love; let him rebuke me — it is oil for my head; let me not refuse it. Even now my prayer is against the evil acts of the wicked.

6When their rulers will be thrown off the sides of a cliff, the people will listen to my words, for they are pleasing.
