Deuteronomy 23:21-23

21 a“If you make a vow to the Lord your God, you shall not delay fulfilling it, for the Lord your God will surely require it of you, and you will be guilty of sin. 22But if you refrain from vowing, you will not be guilty of sin. 23You shall be careful to do what has passed your lips, for you have voluntarily vowed to the Lord your God what you have promised with your mouth.

Ecclesiastes 9:2

2 bIt is the same for all, since cthe same event happens to the righteous and the wicked, to the good and the evil,
Septuagint, Syriac, Vulgate; Hebrew lacks  and the evil
to the clean and the unclean, to him who sacrifices and him who does not sacrifice. As the good one is, so is the sinner, and he who eswears is as he who shuns an oath.

James 5:12

12But above all, my brothers, fdo not swear, either by heaven or by earth or by any other oath, but let youryesbe yes and your “no” be no, so that you may not fall under condemnation.
