Know'st thou what thou hast done, thou dark-hair'd child?
What great events on thy compassion hung?
What prowess lurks beneath yon aspect mild,
And in the accents of that foreign tongue?
As little knew the princess who descried
A floating speck on Egypt's turbid tide,
A bulrush-ark the matted reeds among,
And, yielding to an infant's tearful smile,
Drew forth Jehovah's seer from the devouring Nile.
