1 Kings 3:23-25

Then said the king, The one saith, This is my son that liveth, and thy son is the dead: and the other saith, Nay; but thy son is the dead, and my son is the living. And the king said, Fetch me a sword. And they brought a sword before the king. And the king said, Divide the living child in two, and give half to the one, and half to the other.
