12 And before all things, my brethren, do not swear, neither by the heaven, neither by the earth, neither by any other oath, and let your Yes be Yes, and the No, No; that under judgment ye may not fall.
12
Above all, my brothers and sisters, do not swear—not by heaven or by earth or by anything else. All you need to say is a simple “Yes” or “No.” Otherwise you will be condemned.
