'Invaders' in the Bible

Your land is devastated, your cities burned with fire. Right before your eyes your crops are being destroyed by foreign invaders. They leave behind devastation and destruction.

Now in that day [because of the poverty caused by the invaders] a man will keep alive only a young milk cow and two sheep;

So I weep along with Jazer over the vines of Sibmah. I will saturate you with my tears, Heshbon and Elealeh, for the conquering invaders shout triumphantly over your fruit and crops.

But the horde of invaders will be like fine dust, the horde of tyrants like chaff that is blown away. It will happen suddenly, in a flash.
