Make me know my days

O Lord, make me know my end
and what is the measure of my days;
let me know how fleeting I am!
Behold, you have made my days a few handbreadths,
and my lifetime is as nothing before you.
Surely all mankind stands as a mere breath! Selah
Surely a man goes about as a shadow!
Surely for nothing they are in turmoil;
man heaps up wealth and does not know who will gather!
“And now, O Lord, for what do I wait?
My hope is in you.

Psalm 39.4-7a

I love you, O Lord, my strength.
The Lord is my rock and my fortress and my deliverer,
my God, my rock, in whom I take refuge,
my shield, and the horn of my salvation, my stronghold ...
This God—his way is perfect;
the word of the Lord proves true;
he is a shield for all those who take refuge in him.
