'Swears' in the Bible

Or if anyone swears [an oath] thoughtlessly or impulsively aloud that he will do either evil or good, in whatever manner a person may speak thoughtlessly or impulsively with an oath, but he is unaware of it, when he recognizes it, he will be guilty in one of these.

or has found what was lost and lied about it and sworn falsely, so that he sins in regard to any one of the things a man may do—

If a man makes a vow to the Lord or swears an oath to bind himself with a pledge [of abstinence], he shall not break (violate, profane) his word; he shall do according to all that proceeds out of his mouth.

“If a man sins against his neighbor and is made to take an oath [of innocence] and he comes to take the oath before Your altar in this house (temple),

In his eyes an evil person is despised,But he honors those who fear the Lord [and obediently worship Him with awe-inspired reverence and submissive wonder].He keeps his word even to his own disadvantage and does not change it [for his own benefit];

But the king will rejoice in God;Everyone who swears by Him [honoring the true God, acknowledging His authority and majesty] will glory,For the mouths of those who speak lies will be stopped.

It is the same for all. There is one fate for the righteous and for the wicked; for the good, for the clean and for the unclean; for the man who offers sacrifices and for the one who does not sacrifice. As the good man is, so is the sinner; as he who swears an oath is, so is he who is afraid to swear an oath.

Then he said to me, “This is the curse that is going out over the face of the whole land; for everyone who steals will be cut off according to the writing on one side, and everyone who swears [oaths falsely] shall be cut off according to the writing on the other side.

I will send the curse out,” declares 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; and it will spend the night in that house and consume it, both its timber and its stones.”
