Under
In the Bible, things that are lower down, or under, physically, generally represent things that are lower or more external spiritually. In some cases, the lower things have been separated and put away to protect the good, but in others, it can mean that a less exalted idea or good desire is supporting a more exalted one.

Ezekiel 31:14
14
to the end that none of all the trees by the waters exalt themselves in their stature, neither set their top among the thick boughs, nor that their mighty ones stand up on their height, [even] all who drink water: for they are all delivered to death, to the lower parts of the earth, in the midst of the children of men, with those who go down to the pit.
