Psalms 39:3-4

³Mine heart was hot within me; and fire shall burn out in my thinking. I spake in my tongue; (My heart was hot within me; and the fire burned forever as I thought about all this. And then I said with my tongue,)

⁴Lord, make thou mine end known to me. And the number of my days, what it is; that I know, what faileth to me, (or so that I know, what falleth to me, or so that I know, when I shall fail, or die).
