"Furthermore, you're aware of what Zeruiah's son Joab did to me and to those two commanders of the armies of Israel, Ner's son Abner and Jether's son Amasa, whom he killed, and how he shed the blood of wartime during times of peace, staining the very belt he wears around his waist and the sandals he wears on his feet.

Beh-hadad sent this message back: "May the gods do so to me, and more than that also, if the dust that remains of Samaria is enough to fill up a few handfuls for all of the armies at my disposal."

The armies were deployed opposite each other for seven days. On the seventh day the battle began, and the Israelites killed 100,000 Syrian foot soldiers in one day.
