References for Jeremiah 46:2
"Buckle on your armor and advance into battle!
Harness the horses, and prepare to mount them. Put on your helmets, sharpen your spears, and prepare your armor.
But look! The Egyptian army flees in terror. The bravest of its fighting men run without a backward glance. They are terrorized at every turn, says the LORD.
The swiftest cannot flee; the mightiest warriors cannot escape. By the Euphrates River to the north they stumble and fall."
