James 5:10-12

My brethren, take the prophets, who spoke in the name of the Lord, as an example of suffering and patience. Indeed we count them blessed who endure. You have heard of the perseverance of Job and seen the end intended by the Lord—that the Lord is very compassionate and merciful. But above all, my brethren, do not swear, either by heaven or by earth or with any other oath. But let your “Yes” be “Yes,” and your “No,” “No,” lest you fall into judgment.
