And they shall be afraid - The Jews, or the party or faction among the Jews, that were expecting aid from allied Ethiopia and Egypt. When they shall see them vanquished, they shall apprehend a similar danger to themselves; and they shall be ashamed that they ever confided in a people so little able to aid them, instead of trusting in the arm of God.
Egypt their glory - Their boast, as if Egypt was able to save them. The word rendered here ‘glory’ (תפארת tiph'ereth) means properly, “ornament, praise, honor;” and then it may mean the “object” of glory, or that in which people boast or confide. That is its sense here (compare Isaiah 10:12; Isaiah 13:19; Zechariah 12:7).
