At the noise of the stamping of the hoofs of his strong horses, at the rushing of his chariots, and at the rumbling of his wheels, the fathers shall not look back to their children for feebleness of hands; The stamping of the hoofs - At the galloping sound, -
Quadrupedante putrem sonitu quatit ungula campum,
is a line of Virgil, (Aen. 8:596), much celebrated; and quoted here by Blayney, where the galloping sound of the horses' hoofs is heard. In the stamping of the horses, the rushing of the chariots, and the rumbling of the wheels, our translators intended to convey the sense by the sound of the words, and they have not been unsuccessful. Their translation of the original is at the same time sufficiently literal.
The fathers shall not look back - Though their children are left behind, they have neither strength nor courage to go back to bring them off.
