'Herself' in the Bible

And Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also?

Said he not himself unto me, She is my sister? And she, even she herself said, He is my brother. In the integrity of my heart and the innocency of my hands have I done this.

And she said unto the servant, What man is this that walketh in the field to meet us? And the servant said, It is my master. And she took her veil, and covered herself.

And she put off from her the garments of her widowhood, and covered herself with her veil, and wrapped herself, and sat in the gate of Enaim, which is by the way to Timnah; for she saw that Shelah was grown up, and she was not given unto him to wife.
