Psalm 39:1-6

I said, I will look to my ways,
lest with my tongue I sin:
In sight of wicked men my mouth
with bridle I'll keep in.
2 With silence I as dumb became,
I did myself restrain
From speaking good; but then the more
increasèd was my pain.

3 My heart within me waxèd hot;
and, while I musing was,
The fire did burn; and from my tongue
these words I did let pass:
4 Mine end, and measure of my days,
O Lord, unto me show
What is the same; that I thereby
my frailty well may know.

5 Lo, thou my days an handbreadth mad'st;
mine age is in thine eye
As nothing: sure each man at best
is wholly vanity.
6 Sure each man walks in a vain show;
they vex themselves in vain:
He heaps up wealth, and doth not know
to whom it shall pertain.
