Albert Barnes Commentary Jeremiah 4:6

"Set up a standard toward Zion: flee for safety, stay not; for I will bring evil from the north, and a great destruction." — Jeremiah 4:6 (ASV)

The standard - A flag or signal, to which the people were to rally. Retire, stay not - Rather, gather your goods together: linger not; “for I” (emphatic, Yahweh) am bringing at this very time and so forth.
