Riddle 56

The vast hosts of Egypt, at Pharaoh’s decree,
All blazing in armor marched down to the sea.
The plot was devised in a moment of rage,
By my last, who committed my first ’gainst a sage.
A dry way through the sea for the hosts was revealed;
But this availed naught, for their dark doom was sealed;
The furious billows no power could control,
And ’neath the dark waters they soon were my whole.
