For the sword of the enemy - literally, “for to the enemy a sword; i. e., for the enemy is armed,” he has a commission from God to execute judgment. See Jeremiah 12:12; Isaiah 10:5, and Psalms 17:13 note.
Fear is on every side - Magor-Missabib, Jeremiah’s watchword (compare Jeremiah 20:3, Jeremiah 20:10). The “and” before it should be omitted.
