James 4 11 16

¹¹ Do not speak evil against one another, brothers. The one who speaks against a brother or judges his brother, speaks evil against the law and judges the law. But if you judge the law, you are not a doer of the law but a judge.
¹² There is only one lawgiver and judge, he who is able to save and to destroy. But who are you to judge your neighbor?
¹³ Come now, you who say, “Today or tomorrow we will go into such and such a town and spend a year there and trade and make a profit” —
¹⁴ yet you do not know what tomorrow will bring. What is your life? For you are a mist that appears for a little time and then vanishes.
¹⁵ Instead you ought to say, “If the Lord wills, we will live and do this or that.”
¹⁶ As it is, you boast in your arrogance. All such boasting is evil.
