The 'moon' in one sense signifies self-derived intelligence and faith grounded in a person's self. The 'moon' also signifies the Lord in reference to faith, and thus faith in the Lord. It can additionally mean mean spiritual good or truth.

'Until the moon is not,' as in Psalm 72:5, means that faith would become love.
