John Trapp on Isaiah 62:5

Ver. 5. For as a young man marrieth a Virgin, ſo ſhall thy Sons marry thee] This tranſlation (ſaith one who preferreth the Vulgar, The young man ſhall dwell with the Virgins) marreth the ſenſe: ſith it is improper to ſay of ſons, that they ſhall marry their mother. But I ſay that the Church never flouriſheth more, than when the ſon marrieth the mother, and doth his utmoſt to beautifie and amplifie her. See 2 Cor. 11.2.

And as the Bridegroom rejoyceth over the Bride, ſo ſhall thy God rejoyce over thee] Communicating with our ſouls his ſweeteſt favours in his Ordinances, as in the Bridal-bed, and making us to be conceived with the fruits of righteouſneſſe to everlaſting life. It is therefore a moſt unworthy thing, that men ſhould go a whoring from under him, Hoſ. 4.12. and ſeek to themſelves among the creatures, alias delieias & amaſias other ſweet-hearts.
