'Lowest' in the Bible

Therefore the Lord cuts off head and tail [the highest and the lowest] from Israel,Both [the high] palm branch and [the low] bulrush in one day.

But you, like a birth before its time, are stretched out with no resting-place in the earth; clothed with the bodies of the dead who have been put to the sword, who go down to the lowest parts of the underworld; a dead body, crushed under foot.
