Thy God ... will deliver thee - The heathen believed in the interposition of the gods at times in favor of their worshippers. Darius recognized Daniel’s God as a god, but not the only true God. He had heard of the deliverance of the three youths in Dan 3:26, Dan 3:27 and hence augurs Daniel’s deliverance. I am not my own master, and cannot deliver thee, however much I wish it. “Thy God will.” Kings are the slaves of their flatterers. Men admire piety to God in others, however disregarding Him themselves.
