Male and female
Because of their understanding of spiritual marriage, the people of the Most Ancient church perceived 'male and female' as two faculties in the spiritual self: 'male' refers to the understanding and 'female,' to the will. When these faculties act as one, they called it 'marriage.'
Waters, rivers, and depths
'Waters,' 'rivers,' and 'depths,' as in Psalm 78:15-16, signify truths from the Lord.
