'Alone' in the Bible

And when she came to the man of God to the hill, she caught him by the feet: but Gehazi came near to thrust her away. And the man of God said, Let her alone; for her soul is vexed within her: and the LORD hath hid it from me, and hath not told me.

And Hezekiah prayed before the LORD, and said, O LORD God of Israel, which dwellest between the cherubims, thou art the God, even thou alone, of all the kingdoms of the earth; thou hast made heaven and earth.

And he said, Let him alone; let no man move his bones. So they let his bones alone, with the bones of the prophet that came out of Samaria.
