'Herself' in the Bible

So Sarah laughed to herself [when she heard the Lord’s words], saying, “After I have become old, shall I have pleasure and delight, my lord (husband) being also old?”

Did Abraham not tell me, ‘She is my sister?’ And she herself said, ‘He is my brother.’ In the integrity of my heart and innocence of my hands I have done this.”

She said to the servant, “Who is that man there walking across the field to meet us?” And the servant said, “He is my master [Isaac].” So she took a veil and covered herself [as was customary].

So she removed her widow’s clothes and covered herself with a veil, and wrapped herself up [in disguise], and sat in the gateway of Enaim, which is on the road to Timnah; for she saw that Shelah had grown up, and she had not been given to him as a wife [as Judah had promised].

Then Judah said, “Let her keep the things (pledge articles) for herself, otherwise we will be a laughingstock [searching everywhere for her]. After all, I sent this young goat, but you did not find her.”
