Psalms 39:1-4

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. I was dumb with silence, I held my peace, even from good; And my sorrow was stirred. My heart was hot within me; While I was musing the fire burned; Then spake I with my tongue: Jehovah, make me to know mine end, And the measure of my days, what it is; Let me know how frail I am.
