He delivereth and rescueth - As in the case of Daniel. This attribute would of course be prominent in the view of Darius, since so remarkable an instance of his power had been recently manifested in rescuing Daniel.
And he worketh signs and wonders ... - Performs miracles far above all human power. If he had done it on earth in the case of Daniel, it was fair to infer that he did it also in heaven. Compare the notes at Daniel 4:2-3.
The power of the lions - Margin, hand. The hand is the instrument of power. The word paw would express the idea here, and would accord with the meaning, as it is usually with the paw that the lion strikes down his prey before he devours it.
