[Matthew 5:33:37] Again you have heard that it was said to those of old, You shall not swear falsely, but shall perform your oaths to the Lord.’ But I say to you, do not swear at all: neither by heaven, for it is God’s throne; nor by the earth, for it is His footstool; nor by Jerusalem, for it is the city of the great King. Nor shall you swear by your head, because you cannot make one hair white or black. But let your ‘Yes’ be ‘Yes,’ and your ‘No,’ ‘No.’ For whatever is more than these is from the evil one.

[Deuteronomy 23:21-22] When you make a vow to the LORD your God, you shall not delay to pay it; for the LORD your God will surely require it of you, and it would be sin to you. But if you abstain from vowing, it shall not be sin to you.

[James 5:12] 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.
