'Myself' in the Bible

So I bought her for myself for fifteen pieces of silver and a homer and a half of barley.

For I will be to Ephraim like a lion, and like a young lion to the house of Judah. I myself will tear in pieces and go away. I will carry off, and there will be no one to deliver.

Ephraim said, "Surely I have become rich, I have found myself wealth. In all my wealth they won't find in me any iniquity that is sin."
