So ſhall the King of Aſſyria led away] As men uſe to lead or drive cattel, for ſo the Hebrew word Nahag importeth; ſo are poor captives led: and ſo ſhall the Lord alſo one day lead forth with or in company of the workers of iniquity (notorious offendors) all ſuch as turn aſide unto their crooked wayes, Hypocrites and diſſemblers: when as peace ſhall be upon Iſrael, upon the pure in heart, Pſalm 125.5.
