Salmos 39

4 LORD, make me to know my end and the measure of my days, what it [is that] I may know how long I am to be of this world.

5 Behold, thou hast made my days [as] a handbreadth, and my age [is] as nothing before thee; verily every man that lives [is] altogether vanity. Selah.

6 Surely man walks in darkness; surely they are disquieted in vain; they heap up [riches] not knowing who shall gather them.
