I will scatter them also among the heathen, whom neither they nor their fathers have known: and I will send a sword after them, till I have consumed them.
Nor their fathers have known - alluding to Jeremiah 9:14, "Their fathers taught them" idolatry; therefore the children shall be scattered to a land which "neither their fathers nor they have known."
Send a sword after them - not even in flight shall they be safe.
