'Lower' in the Bible

(Now this, He went up, what is it but that he first went down into the lower parts of the earth?

You made him a little lower than the angels; you gave him a crown of glory and honour, and made him ruler over all the works of your hands:

But we see him who was made a little lower than the angels, even Jesus, crowned with glory and honour, because he let himself be put to death so that by the grace of God he might undergo death for all men.
