'Someone' in the Bible

So Gehazi ran after Naaman. When Naaman noticed someone running after him, he came down from his chariot, greeted him and asked, "Is everything all right?"

Someone asked, "Would you be willing to come with your servants?"

Later on, Elisha traveled to Damascus. King Ben-hadad of Aram was ill, but someone informed him, "The man of God has come here!"
