And which of you by being anxious can add one cubit unto the measure of his life?
Which of you by taking thought can add one cubit unto his stature?
And who of you by worrying and being anxious can add one unit of measure (cubit) to his stature or to the span of his life? [Ps. 39:5-7.]
Who among you by worrying can add a single moment to your life?
And which of you, by thinking, is able to add one cubit to his stature?
