'Livest' in the Bible

Take heed to thyself that thou forsake not the Levite as long as thou livest upon the earth.

And Uriah said unto David, The ark, and Israel, and Judah, abide in tents; and my lord Joab, and the servants of my lord, are encamped in the open fields; shall I then go into mine house, to eat and to drink, and to lie with my wife? as thou livest, and as thy soul liveth, I will not do this thing.
