John Trapp on Isaiah 43:13

Ver. 13. Yea before the day was I am He] The Ancient of dayes, yea the Eternal. The God of Iſrael was long before Iſrael was in being.

And there is none that can deliver out of my hand] So Nebuchadnezzar vainly vaunted, but was ſoon confuted, Dan. 3.15, 17, 29.

I will work and who ſhall let it?] Angels may be hindered: God can come between their Eſſence and their executive power, and ſo keep them from doing what they would. In fire there is the ſubſtance, and the quality of heat: between theſe God can ſeparate: as he did in the Babyloniſh fire, Dan. 2. But who ſhall hinder the moſt High?
