'She conceived again and bore a son', as previously, means spiritual conception and birth from what is external towards that which is more internal still. 'And she said, Now this time my husband will cling to me' means in the highest sense love and mercy, in the internal sense charity, in the external sense a joining together - spiritual love being meant here. 'For I have borne him three sons' means that which happens next. 'Therefore she called his name Levi' means the essential nature of it.
