John Trapp on Joel 3:19

Verſe 19. Egypt ſhall be a deſolation,] By Egypt and Edom, are meant all Chriſts adverſaries, whether they be profeſſed open enemies as were the Egyptians, or falſe brethren as the Edomites. Romiſts have been both, and ſhall therefore be deſolated, Rev. 17.16. with 11.8.

For the violence againſt the children of Judah,] From the very cradle of the Church, Exod. 1. yea ſooner: for Eſau in the very womb juſtled his brother Jacob, and offered violence againſt him, that he might loſe no time.

becauſe they have ſhed innocent blood in the land.] The Saints blood is called, innocent blood; 1. Becauſe their ſinnes are remitted. 2. Becauſe they are cauſeleſly killed. And this is a land-deſolating ſinne. The innocent blood ſpilt by Manaſſeh, brought the captivity: the Marian times, our late troubles. The blood of the Martyrs, ſhed by Turk and Pope (whom the Jew-Doctors underſtand by Egypt and Edom here) ſhall be the ruine of them both.
