John Trapp on Isaiah 2:7

Ver. 7. Their land alſo is full of ſilver] They had forſaken the Fountain of Living Waters, and now they hew them out broken Ciſterns: they have made their gold their God, which is a more ſubtile kind of Idolatry, Col. 3.5. dum ſibi ipſis numen quoddam lararium conflant. But though their houſes were full of ſilver and gold, their hearts were not: for they were vext with the curſe of unſatisfiableneſs, Eccleſ. 5.10.

Auri nempe fames parto fit major ab auro.Prudentius.

Neither is there any end of their Treaſures] Joſephus ſaith that there was a world of money found at Ieruſalem when taken by the Romans: ſo there was at Conſtantinople when taken by the Turks; and therefore taken, becauſe the Inhabitants could not find in their heatts to part with it, though for their own defence.

Their land alſo is full of horſes] and their hearts of creature confidence, truſt in the arm of fleſh as Joſephus teſtifieth, that the Jews were this way very faulty, about the time of the laſt devaſtation.
