Psalms 38:3-7

³I was dumb, and humbled myself, and kept silence from good words; and my grief was renewed.

⁴My heart grew hot within me, and a fire would kindle in my meditation: I spoke with my tongue,

⁵O Lord, make me to know mine end, and the number of my days, what it is; that I may know what I lack.

⁶Behold, thou hast made my days old; and my existence is as nothing before thee: nay, every man living is altogether vanity. Pause.

⁷Surely man walks in a shadow; nay, he is disquieted in vain: he lays up treasures, and knows not for whom he shall gather them.
