'Oh' in the Bible

The one woman said, “Oh, my lord, this woman and I live in the same house; and I gave birth to a child while she was in the house.

The woman whose child was still alive cried out to the king, because her heart yearned for her son. "Oh no, your majesty!" she said. "Give her the living child. Please don't kill him." But the other woman said, "Cut him in half! That way, he'll belong to neither one of us."

Then he laid the corpse in his own grave, and they mourned over him: “Oh, my brother!”
