James 4:14
King James Version
“Whereas ye know not what on the morrow. For what your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.”
Context
11Speak not evil one of another, brethren. He that speaketh evil of brother, and judgeth his brother, speaketh evil of the law, and judgeth the law: but if thou judge the law, thou art not a doer of the law, but a judge.
12There is one lawgiver, who is able to save and to destroy: who art thou that judgest another?
13Go to now, ye that say, To day or to morrow we will go into such a city, and continue there a year, and buy and sell, and get gain:
14Whereas ye know not what on the morrow. For what your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.
15For that ye to say, If the Lord will, we shall live, and do this, or that.
16But now ye rejoice in your boastings: all such rejoicing is evil.
17Therefore to him that knoweth to do good, and doeth not, to him it is sin.
