James 1:25

1:25 But the one who peers into the perfect law of liberty and fixes his attention there, and does not become a forgetful listener but one who lives it out – he will be blessed in what he does.

James 5:12

5:12 And above all, my brothers and sisters, do not swear, either by heaven or by earth or by any other oath. But let your “Yes” be yes and your “No” be no, so that you may not fall into judgment.
