'Short' in the Bible

“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]! Selah.

Remember how fleeting my lifetime is;For what vanity, [for what emptiness, for what futility, for what wisp of smoke] You have created all the sons of men!
