'Someone' in the Bible

Then he himself went to Ramah and came as far as the large well that is in Secu; and he asked and said, “Where are Samuel and David?” And someone said, “Behold, they are at Naioth in Ramah.”

Then the king sent someone to summon Ahimelech the priest, the son of Ahitub, and all his father’s household, the priests who were in Nob; and all of them came to the king.
