This psalm of David is a sincere prayer asking God to help him control his tongue (“set a guard over my mouth, O Lord”) and to help him to resist temptation (“Let not my heart be drawn to what is evil”). David then expresses that being corrected by a righteous man is a kindness (let him rebuke me – it is oil on my head”) and he concludes saying that he takes refuge in the Lord asking God to keep him free from the traps of evildoers.
