'Downward' in the Bible

And the remnant that is escaped of the house of Judah shall yet again take root downward, and bear fruit upward.

Who knoweth the spirit of man that goeth upward, and the spirit of the beast that goeth downward to the earth?

And the remnant that is escaped of the house of Judah shall again take root downward, and bear fruit upward:

And I saw as the colour of amber, as the appearance of fire round about within it, from the appearance of his loins even upward, and from the appearance of his loins even downward, I saw as it were the appearance of fire, and it had brightness round about.

Then I beheld, and lo a likeness as the appearance of fire: from the appearance of his loins even downward, fire; and from his loins even upward, as the appearance of brightness, as the colour of amber.
