3. The relentlessness of the army 2:6-9

2:6 As this army advanced, all the people in and around Jerusalem felt terrified and turned pale with fear (cf. Isa. 26:17; Jer. 4:31; Mic. 4:10).

2:7-9 The enemy soldiers ran with great stamina and climbed over walls, as locusts do. They were very disciplined in their attack, each one staying in his proper position and not crowding his fellow soldiers (cf. Josh. 6:5). Even when they broke through an obstacle they did not break ranks. They rushed on the city of Jerusalem, ran along its walls, climbed into its houses like so many thieves. Again the comparison with locusts is striking.
