Psalms 17:14; Psalms 39:5; Psalms 89:47

14 From men which are thy hand, O LORD, from men of the world, which have their portion in this life, and whose belly thou fillest with thy hid treasure: they are full of children, and leave the rest of their substance to their babes.

5 Behold, thou hast made my days as an handbreadth; and mine age is as nothing before thee: verily every man at his best state is altogether vanity. Selah.

47 Remember how short my time is: wherefore hast thou made all men in vain?
