(KJV)
I said, I will take heed to my ways, 
LORD, make me to know mine end, 
and the measure of my days, what it is: 
that I may know how frail I am.
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.
Surely every man walketh in a vain shew: 
surely they are disquieted in vain: 
he heapeth up riches, 
and knoweth not who shall gather them.
And now, Lord, what wait I for? my hope is in thee.
Deliver me from all my transgressions: 
make me not the reproach of the foolish.
I was dumb, I opened not my mouth; 
because thou didst it.
Remove thy stroke away from me: 
I am consumed by the blow of thine hand.
When thou with rebukes dost correct man for iniquity, 
Thou makest his beauty to consume away like a moth: 
surely every man is vanity. 
Selah.
Hear my prayer, O LORD, and give ear unto my cry; 
hold not thy peace at my tears: 
for I am a stranger with thee, and a sojourner, 
as all my fathers were.
O spare me, that I may recover strength, 
before I go hence, and be no more.
