Psalm 39:4-6

Amplified Bible

⁴ 
“Lord, let me know my [life’s] end
And [to appreciate] the extent of my days;
Let me know how frail I am [how transient is my stay here].
⁵ 
“Behold, You have made my days as [short as] hand widths,
And my lifetime is as nothing in Your sight.
Surely every man at his best is a mere breath [a wisp of smoke, a vapor that vanishes]!^(A) Selah.
⁶ 
“Surely every man walks around like a shadow [in a charade];
Surely they make an uproar for nothing;
Each one builds up riches, not knowing who will receive them.^(B)
