James 4:14 in the King James Version
Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.
Context
13 Come now, you who say, “Today or tomorrow let’s go into this city and spend a year there, trade, and make a profit.”
14 Yet you don’t know what your life will be like tomorrow. For what is your life? For you are a vapor that appears for a little time and then vanishes away.
15 For you ought to say, “If the Lord wills, we will both live, and do this or that.”
