'Sworn' in the Bible

He who has clean hands and a pure heart,Who has not lifted up his soul to falsehoodAnd has not sworn deceitfully.

“I have made a covenant with My chosen;I have sworn to David My servant,

“Once I have sworn by My holiness;I will not lie to David.

The Lord has sworn and will not change His mind,“You are a priest foreverAccording to the order of Melchizedek.”

I have sworn and I will confirm it,That I will keep Your righteous ordinances.

The Lord has sworn to DavidA truth from which He will not turn back:“Of the fruit of your body I will set upon your throne.
