Let his posterity, &c. His posterity shall be cut off, &c: they suffered an excision by the Roman sword, and in the generation following, their name, as a church, and civil polity, were blotted out of the list of states and kingdoms. Let the iniquity of his father be remembered Hebrew, יזכר, it shall be remembered against him, or punished in him, as God had threatened to deal with great delinquents, Exodus 20:5. Let them be יהיו, they shall be, namely, the sins of his parents last mentioned; before the Lord In God's sight and memory, to provoke him to punish them: they shall not be covered nor pardoned. That upon them, as Christ foretold, might come all the righteous blood shed from the blood of righteous Abel; &c., Matthew 22:25. For “the blood of the prophets cried for vengeance against those who crucified the Lord of the prophets.”
