The precept of the law, therefore, is to be taken
in a more spiritual sense. For there is spiritual seed which is
conceived through the love and fear of God in the spiritual womb,
travailing and bringing forth the spirit of salvation. And in
this sense must be understood this verse: Blessed is he who
hath seed in Zion and posterity in Jerusalem. For does it
mean that, although he be a whoremonger and a drunkard and an idolater,
he is still blessed if only he hath seed in Sion and posterity in
Jerusalem? No one in his senses will say this.
