For the director of music. For Jeduthun. A psalm of David.

1 aI said, “I will watch my ways and keep my tongue from sin; I will put a muzzle on my mouth while in the presence of the wicked.”
2 So I remained utterly silent, not even saying anything good. But my anguish increased;
3 my heart grew hot within me. While I meditated, the fire burned; then I spoke with my tongue:
4 “Show me, LORD, my life’s end and the number of my days; let me know how fleeting my life is.
