Charles Ellicott Commentary Jeremiah 46:19

"O thou daughter that dwellest in Egypt, furnish thyself to go into captivity; for Memphis shall become a desolation, and shall be burnt up, without inhabitant." — Jeremiah 46:19 (ASV)

O you daughter dwelling in Egypt. — As in Jeremiah 46:11, the daughter is Egypt itself personified. She is to prepare herself (literally, with the instruments of captivity), as with “bag and baggage” for a long journey. (Compare to Ezekiel 12:3.) Noph (= Memphis) is to be left as a depopulated city.
