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.

Arcana Coelestia # 912
912. 'Bring out with you' means their state of freedom. This is clear from what has been stated about 'going out of the ark' in verse 15 above meaning freedom.
