'Swears' in the Bible

Or if someone swears rashly to do what is good or evil—concerning anything a person may speak rashly in an oath—without being aware of it, but later recognizes it, he incurs guilt in such an instance.

or finds something lost and lies about it; or swears falsely about any of the sinful things a person may do—

When a man makes a vow to the Lord or swears an oath to put himself under an obligation, he must not break his word; he must do whatever he has promised.

Whoever is blessed in the landwill be blessed by the God of truth,and whoever swears in the landwill swear by the God of truth.For the former troubles will be forgottenand hidden from My sight.

Then he said to me, “This is the curse that is going out over the whole land, for every thief will be removed according to what is written on one side, and everyone who swears falsely will be removed according to what is written on the other side.

I will send it out,”—this is the declaration of the Lord of Hosts—“and it will enter the house of the thief and the house of the one who swears falsely by My name. It will stay inside his house and destroy it along with its timbers and stones.”
