Jeremiah 4:11-18

Verse 11

A dry wind - a fall wind - as clouds - as a whirlwind - All these expressions appear to refer to the pestilential winds, suffocating vapors, and clouds and pillars of sand collected by whirlwinds, which are so common and destructive in the east, (see on Isa 21:1 (note)); and these images are employed here to show the overwhelming effect of the invasion of the land by the Chaldeans.
Verse 13

Wo unto us! - The people, deeply affected with these threatened judgments, interrupt the prophet with the lamentation - Wo unto us, for we are spoiled! The prophet then resumes: -
Verse 14

O Jerusalem, wash thine heart - Why do ye not put away your wickedness, that ye may be saved from these tremendous judgments? How long shall thy vain thoughts of safety and prosperity lodge within thee? Whilst thou continuest a rebel against God, and provokest him daily by thy abominations!
Verse 15

For a voice declareth from Dan - Dan was a city in the tribe of Dan, north of Jerusalem; the first city in Palestine, which occurs in the way from Babylon to Jerusalem.

Verse 16

Watchers come from a far country - Persons to besiege fortified places.
Verse 17

As keepers of a field - In the eastern countries grain is often sown in the open country; and, when nearly ripe, guards are placed at different distances round about it to preserve it from being plundered. Jerusalem was watched, like one of these fields, by guards all round about it; so that none could enter to give assistance, and none who wished to escape were permitted to go out.
