'Thyself' in the Bible

But Jonathan Saul's son delighted much in David. And Jonathan told David, saying, Saul my father seeks to kill thee; and now, I pray thee, take heed to thyself in the morning, and abide in a secret place and hide thyself;

Deal kindly then with thy servant; for thou hast brought thy servant into a covenant of Jehovah with thee; but if there be in me iniquity, slay me thyself; for why shouldest thou bring me to thy father?

but on the third day thou shalt go down quickly, and come to the place where thou didst hide thyself on the day of the business, and abide by the stone Ezel.

And now, my lord, as Jehovah liveth, and as thy soul liveth, seeing Jehovah has restrained thee from coming with bloodshed, and from avenging thyself with thine own hand, now let thine enemies, and they that seek evil to my lord, be as Nabal.
