Matthew 5:33-34
Oaths
5:33 “Again, you have heard that it was said to an older generation, ‘Do not break an oath, but fulfill your vows to the Lord.’
5:34 But I say to you, do not take oaths at all – not by heaven, because it is the throne of God,
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.
