'As Your Soul Lives' in the Bible

Uriah said to David, "The ark, Israel, and Judah, are staying in tents; and my lord Joab, and the servants of my lord, are encamped in the open field. Shall I then go into my house to eat and to drink, and to lie with my wife? As you live, and as your soul lives, I will not do this thing!"

The king said, “Is the hand of Joab with you in all of this?” And the woman answered, “As your soul lives, my lord the king, no one can turn to the right or to the left from anything that my lord the king has said. Indeed, it was your servant Joab who commanded me; he put all these words in the mouth of your maidservant.

"As your soul lives, your majesty, the king," the woman answered, "no one can divert anything left or right from what your majesty the king has spoken! As a matter of fact, it was your servant Joab! He was there, giving me precise orders about everything that your humble servant was to say. Your servant Joab did this, intending to change the outcome of this matter. Nevertheless, your majesty is wise, like the wisdom of the angel of God, to be aware of everything that's going on throughout the earth."
