'Herself' in the Bible

Sarah laughed within herself, saying, "After I have grown old will I have pleasure, my lord being old also?"

Didn't he tell me, 'She is my sister?' She, even she herself, said, 'He is my brother.' In the integrity of my heart and the innocence of my hands have I done this."

She said to the servant, "Who is the man who is walking in the field to meet us?" The servant said, "It is my master." She took her veil, and covered herself.

She took off of 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 wasn't given to him as a wife.
