'As the Lord Lives' in the Bible

Then the king swore an oath and said, “As the Lord lives, who has redeemed my soul from all distress,

So now, as the Lord lives, who has established me and set me on the throne of David my father, and who has made me a house as He promised, Adonijah shall indeed be put to death today.”

But Micaiah said, “As the Lord lives, I will speak what the Lord says to me.”
