Commentary
So he turned away. This means he made himself neglect after his knowledge called him to turn towards it. He indicated his turning away by saying: 'by his strength.' This means because of what he relies on from the power within himself and his supporters and his armies, or by all his armies - a metaphor for exaggeration in neglecting.
And he said, informing of his inability regarding what he was brought with, while he does not realize: 'a magician.' Then he contradicted, as you contradicted, and he said in his ignorance regarding what follows from his saying: 'or a madman.' This means for his audacity against me, despite my great kingdom, with something like this which he calls to and threatens me with.
