Parallel
James 4:14
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
Whereas ye know not what shall be on the morrow. For what is your life? It is even (note: Or, for it is) a vapour, that appeareth for a little time, and then vanisheth away.
You do not even know what will happen tomorrow! What is your life? You are a mist that appears for a little while and then vanishes.
