Help To Know How Frail You Are

Psalm 39:1-4

1  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 murmuring the fire burned: then spake I with my tongue,
4  LORD, make me to know mine end, and the measure of my days, what it is; that I may know how frail I am.
