Psalm 39:4-5

Authorized (King James) Version

⁴ Lord, make me to know mine end,
and the measure of my days, what it is;
that I may know how frail I am.
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.
