2 Samuel 14:11

And she said, Let the king, I pray thee, make mention of the Lord his God, that though avengers of blood be multiplied to destroy, they shall not destroy my son. Whereupon he said, As the Lord liveth, there shall not a hair of thy son’s head fall to the ground.

And she said, Let now the king remember concerning his Lord God in that the avenger of blood is multiplied to destroy, and let them not take away my son. And he said, As the Lord lives, not a hair of thy son shall fall to the ground.
