John Trapp on Isaiah 10:12

Ver. 12. Wherefore] Heb. And. A cloſe connection; where pride is in the ſaddle, there deſtruction is on the crupper. When the ſcum is at higheſt, it falls in the fire.

When the Lord hath performed] When he hath ſufficiently chaſtiſed his children by this rod of his wrath, he will caſt it into the fire. So Jer. 25. when other Nations have drunk deep of the cup of the divine diſpleaſure, Babylon ſhall ſuck up the dreggs. What became of the Primitive Perſecutors and of ſuch as were moſt active here in thoſe dog-dayes of Q. Mary? See the Acts and Monuments of the Church.

Ʋpon mount Sion] For there he uſually beginneth, Jer. 25.18. 1 Pet. 4.17. his own he leaſt of all ſpareth, Am. 3.2.

I will puniſh the fruit of the ſtout heart] His arrogant words and lofty looks, proceeding from the pride of his heart. But let himſelf tell what thoſe fruits are.
