John Trapp on Jeremiah 28:13

Ver. 13. Thou haſt broken the yokes of wood] That were weaker and lighter;

—nunc graviora feres.

But thou ſhalt make for them yokes of Iron] Thou, Jeremy ſhalt, for a type of a cruel, hard and ſtrong bondage. Bonfinius writeth of the Hungarians, Hungar. rer. decad. 4. l. 9. that they are not to be handled gently, or kindly dealt with: ſed virgâ ferreâ in obſequo continenendes eſſe, but kept in order with a rod of Iron. Such were theſe refractory Jews; but they had enough of it ere God had done with them.
