4 Yahweh, make me to know my end, And the measure of my days, what it is; Let me know how frail I am.5 Look, you have made my days [as] handbreadths; And my lifetime is as nothing before you: Surely every man at his best estate is altogether vanity. Selah.6 Surely everyone among man walks in a vain show; Surely they are disquieted in vain: He heaps up [riches], and does not know who will gather them.
