For the LORD your God is God of gods, and Lord of lords, a great God, a mighty, and a terrible, which regardeth not persons, nor taketh reward: God of gods, and Lord of lords - That is, He is the source whence all being and power proceed; every agent is finite but himself; and he can counteract, suspend, or destroy all the actions of all creatures whensoever he pleases. If he determine to save, none can destroy; if he purpose to destroy, none can save. How absolutely necessary to have such a God for our friend!
A great God - mighty - האל הגבר hael haggibbor, the mighty God; this is the very title that is given to our blessed Lord and Savior, Isaiah 9:6.
