'Oh' in the Bible

And the one woman said, Oh, my lord, I and this woman dwell in one house; and I was delivered of a child with her in the house.

Then spake the woman whose the living child was unto the king, for her heart yearned over her son, and she said, Oh, my lord, give her the living child, and in no wise slay it. But the other said, It shall be neither mine nor thine; divide it.
