“As for me, I am going the way of all of the earth. Be strong and be courageous like a man,

Now the king of Aram’s servants said to him, “Their gods are gods of the hill country. That’s why they were stronger than we were. Instead, we should fight with them on the plain; then we will certainly be stronger than they will be.

Raise another army for yourself like the army you lost—horse for horse, chariot for chariot—and let’s fight with them on the plain; and we will certainly be stronger than they will be.” The king listened to them and did so.
