'As I Live' in the Bible

What shall I say? The Lord hath made a promise to me. Yea, and he himself hath performed it. I shall therefore, as long as I live, remember bitterness of my life.

Lift up thine eyes, and look about thee: all these shall gather them together, and come to thee. As truly as I live, sayeth the LORD, thou shalt put them all upon thee as an apparel, and gird them to thee, as an bride doth her jewels.
