Bible Verses About Keeping Your Word

"Or if anyone utters with his lips a rash oath to do evil or to do good, any sort of rash oath that people swear, and it is hidden from him, when he comes to know it, and he realizes his guilt in any of these; when he realizes his guilt in any of these and confesses the sin he has committed,"

Leviticus 5:4-5 ESV

"Moses spoke to the heads of the tribes of the people of Israel, saying, “This is what the Lord has commanded. If a man vows a vow to the Lord, or swears an oath to bind himself by a pledge, he shall not break his word. He shall do according to all that proceeds out of his mouth."

Numbers 30:1-2 ESV

"When you vow a vow to God, do not delay paying it, for he has no pleasure in fools. Pay what you vow. It is better that you should not vow than that you should vow and not pay. Let not your mouth lead you into sin, and do not say before the messenger that it was a mistake. Why should God be angry at your voice and destroy the work of your hands? For when dreams increase and words grow many, there is vanity; but God is the one you must fear."

Ecclesiastes 5:4-7 ESV

"“Again you have heard that it was said to those of old, ‘You shall not swear falsely, but shall perform to the Lord what you have sworn.’ But I say to you, Do not take an oath at all, either by heaven, for it is the throne of God, or by the earth, for it is his footstool, or by Jerusalem, for it is the city of the great King. And do not take an oath by your head, for you cannot make one hair white or black. Let what you say be simply ‘Yes’ or ‘No’; anything more than this comes from evil."

Matthew 5:33-37 ESV
