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.

Spreading the bones
'Spreading the bones before the sun,' as in Jeremiah 8:1, signifies the hellish things possessed by self-loving people.
