'Someone' in the Bible

David sent and inquired about the woman, and [someone] said, "[Is] this not Bathsheba the daughter of Eliam, the wife of Uriah the Hittite?"

Then Absalom would say, "{Oh, that someone would} appoint me as judge in the land, that {anyone} might come to me who had a legal dispute or a case, and I would give him justice."

David {said longingly}, "{Oh that someone would bring me a drink} of water from the well of Bethlehem that [is] at the gate."
