Jeremiah 13:19 - Matthew Poole's English Annotations on the Holy Bible

Either the cities of Judah which lay southward from Chaldea, and therefore their enemies in the next verse are said to come from the north, and this great evil is said to have come from the north; or (as some would have it) the cities of Egypt, which lay yet more southward, so as the Egyptians should neither come with sufficient force to raise the siege, nor should there be any sanctuary or refuge for them in Egypt, but they should certainly be wholly carried into captivity.
