'As Surely As You Live' in the Bible

Uriah answered David, “The ark, Israel, and Judah are dwelling in tents, and my master Joab and his soldiers are camping in the open field. How can I enter my house to eat and drink and sleep with my wife? As surely as you live and by your life, I will not do this!”

The king asked, “Did Joab put you up to all this?”The woman answered. “As you live, my lord the king, no one can turn to the right or left from all my lord the king says. Yes, your servant Joab is the one who gave orders to me; he told your servant exactly what to say.
