1 For the Chief Musician, for Jeduthun. A Psalm of David. I said, I will take heed to my ways, that I sin not with my tongue: I will keep my mouth with a bridle, while the wicked is before me.
2 I was dumb with silence, I held my peace, even from good; and my sorrow was stirred.
3 My heart was hot within me; while I was musing the fire kindled: then spake I with my tongue:
4 LORD, make me to know mine end, and the measure of my days, what it is; let me know how frail I am.
