The gold gathered from battle and lifted to the higher mind is the god-consciousness a person recovers once the lower nature is subdued, and offering it upward is the meditative act of returning every refined energy to its source rather than hoarding it in the ego. What was stripped from the flesh is not spent on the self; it is safeguarded in the still mind where no thief of desire can reach it.
The captains of the ranks are the ordered faculties that gather this treasure and pass it inward until the whole yield rests above appetite. Real wealth in a person is the awareness kept and given back to the higher mind, not the possessions clutched by the body.
Gold: the god consciousness refined out of a person and lifted to the higher mind
The LORD: the higher mind, the right hemisphere that receives what is offered upward
