'First Man' in the Bible

Are thou the first man who was born? Or were thou brought forth before the hills?

For a heavenly agent went down at a certain time into the pool, and agitated the water. Therefore the first man who stepped in after the agitation of the water became well from whatever affliction he had.

And so it is written, The first man Adam developed into a living soul. The last Adam a life giving spirit.

The first man was of the earth, earthly. The second man is the Lord from heaven.
