Jeremiah 47:3
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; 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 chapter belongs in time after Jeremiah 40-45 and before Jeremiah 46. The book does not keep time order, especially after Jeremiah 20, because the rolls were gathered together out of order. That displacement makes no change in the teaching, and the true time is shown clearly by the chapter itself.
The verse depicts the terror, urgency, and confusion caused by an invading army. Its thundering approach comes in the stamping of the hoofs of strong horses, the rushing of chariots, and the rumbling of wheels. The sound is so overwhelming that fathers flee without looking back to their children. They do so for feebleness of hands, because their hands have lost strength and left them weakened and helpless.
