John Gill Commentary 2 Chronicles 20:6

"and he said, O Jehovah, the God of our fathers, art not thou God in heaven? and art not thou ruler over all the kingdoms of the nations? and in thy hand is power and might, so that none is able to withstand thee." — 2 Chronicles 20:6 (ASV)

And said, O Lord God of our fathers Abraham, Isaac, and Jacob, whose covenant God he was:

are you not God in heaven? who dwell and rule there, and do whatever you please in the armies of it:

and do you not rule over all the kingdoms of the Heathens? being King of kings, and Lord of lords, all the world over:

and in your hand is there not power and might, so that none is able to withstand you? his power being infinite, unlimited, and uncontrollable, and so not resistible by finite creatures, at least not so as to be stopped and overcome.
