James 4:11

9 Grieve, mourn, and weep. Turn your laughter to mourning, and your joy to gloom.

10 Humble yourselves before the Lord, and He will exalt you.

Brothers, do not slander one another. Anyone who speaks against his brother or judges him speaks against the law and judges it. And if you judge the law, you are not a practitioner of the law, but a judge of it.

12 There is only one Lawgiver and Judge, the One who is able to save and destroy. But who are you to judge your neighbor?

13 Come now, you who say, “Today or tomorrow we will go to this or that city, spend a year there, carry on business, and make a profit.”

Do read the surrounding verses too, because the context often says more than a single verse.
