'Swore' in the Bible

"I made a covenant with my chosen one; I swore [an oath] to David my servant:

Where [are] your former acts of loyal love, O Lord, [that] you swore to David by your faithfulness?

Therefore I swore in my anger, 'They shall surely not enter into my rest.'"

that he made with Abraham, and by his oath [swore] to Isaac.

How he swore to Yahweh, he vowed to the Mighty One of Jacob:

Yahweh swore [in] truth to David; he will not turn back from it. "One from the fruit of your {body} I will set on your throne.
