'Sworn' in the Bible

The one who has clean hands and a pure heart,who has not set his mind on what is false,and who has not sworn deceitfully.

The Lord said,“I have made a covenant with My chosen one;I have sworn an oath to David My servant:

Once and for allI have sworn an oath by My holiness;I will not lie to David.

The Lord has sworn an oath and will not take it back:“Forever, You are a priestlike Melchizedek.”

I have solemnly swornto keep Your righteous judgments.
