Jeremiah 4:21
How long shall I see the standard, and hear the sound of the trumpet?
How long shall I see the standard,.... "Ensign" or "banner" displayed; either by the watchmen placed on high hills or towers, who, when they see the enemy approaching, lift up their ensign or banner, and blow with their trumpets, to give the people warning and notice of it, and to call them to battle, and that they might prepare for the same, as Kimchi observes; or else by the Chaldean army, which came with colours flying, trumpets blowing, and set in array for battle, which was very terrible, as an army with banners is, Song of Solomon 6:4:
and hear the sound of the trumpet? either of the watchmen giving notice of danger, and summoning to battle, or of the enemy preparing to attack; see 1 Corinthians 14:8.
