'Someone' in the Bible

So Gehazi pursued Naaman. When Naaman saw someone running after him, he got down from the chariot to meet him and asked, “Is everything all right?”

Elisha was sitting in his house, and the elders were sitting with him. The king sent a man ahead of him, but before the messenger got to him, Elisha said to the elders, “Do you see how this murderer has sent someone to cut off my head? Look, when the messenger comes, shut the door to keep him out. Isn’t the sound of his master’s feet behind him?”

As Josiah turned, he saw the tombs there on the mountain. He sent someone to take the bones out of the tombs, and he burned them on the altar. He defiled it according to the word of the Lord proclaimed by the man of God who proclaimed these things.
