Deuteronomy 32:31

For their rock - The gods and pretended protectors of the Romans.

Is not as our Rock - Have neither power nor influence like our God.

Our enemies themselves being judges - For they often acknowledged the irresistible power of that God who fought for Israel. See Exodus 14:25; Numbers 23:8-12, Numbers 23:19-21; 1 Samuel 4:8.

There is a passage in Virgil, Eclog. iv., ver. 58, very similar to this saying of Moses: -

Pan Deus Arcadia mecum si judice certet,

Pan etiam Arcadia dicat se judice victum.

"Should the god Pan contend with me," (in singing

the praises of the future hero, the deliverer,

prophesied of in the Sibylline books), "were even

Arcadia judge, Pan would acknowledge himself to be

vanquished, Arcadia herself being judge."

Our enemies - i. e., the enemies of Moses and the faithful Israelites; the pagan, more especially those with whom Israel was brought into collision, whom Israel was commissioned to "chase," but to whom, as a punishment for faithlessness, Israel was "sold," Deuteronomy 32:30. Moses leaves the decision, whether "their rock" (i. e. the false gods of the pagan to which the apostate Israelites had fallen away) or "our Rock" is superior, to be determined by the unbelievers themselves. For example, see Exodus 14:25; Numbers 23; 24; Joshua 2:9 ff; 1 Samuel 4:8; 1 Samuel 5:7 ff; 1 Kings 20:28. That the pagan should thus be constrained to bear witness to the supremacy of Israel's God heightened the folly of Israel's apostasy.

32:31 Being judges - Who by their dear bought experience have been forced to acknowledge that our God was far stronger than they and their false gods together.
