'Lower' in the Bible

(Now that he ascended, what is it but that he also descended first into the lower parts of the earth?

Thou madest him a little lower than the angels; thou crownedst him with glory and honour, and didst set him over the works of thy hands:

But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
