Job 27:3

All the while my breath [is] in me,.... So long the oath of God would be upon him, or he bound himself under it:

and the spirit of God [is] in my nostrils; which signifies the same thing. The breath of a man is his spirit, and this is of God, the Father of spirits; he first breathed into man the breath of life, and he became a living soul or spirit, Genesis 2:7; it is he that gives life and breath to every man, Acts 17:25, and continues it as long as he pleases, which is a very precarious thing; for it is in his nostrils, where it is drawn to and fro and soon and easily stopped; nor will it always continue, it will some time not be, it will go forth, and then man dies, and returns to the earth, Ecclesiastes 12:7; but as long as there is breath there is life; so that to say this is the same as to say, as long as I live, or have a being, Psalms 104:33; and while that continued, Job looked upon himself under the oath he had taken by the living God.
