John Trapp on Isaiah 57:17

Ver. 17. For the iniquity of his Covetouſneſſe] Or of his Concupiſcence, the ſin of his nature. But covetouſneſſe is a wickedneſſe with a witneſſe; the root of all evil, 1 Tim. 6.10. Timon could ſay, that there were two ſources of all ſin, viz. [non-Latin text not transcribed] covetouſneſſe and vain-glory.

And he went on frowardly in the way of his own heart] i. e. Exco[illegible: 1 letter]atus ſequitur animalem ſuum spiritum, he blindling blundered on, without fear or wit, croſs-grained and irreclaimable.
