Amos 1:6-8

This is what the LORD says: “The people of Gaza have sinned again and again, and I will not let them go unpunished! They sent whole villages into exile, selling them as slaves to Edom. So I will send down fire on the walls of Gaza, and all its fortresses will be destroyed. I will slaughter the people of Ashdod and destroy the king of Ashkelon. Then I will turn to attack Ekron, and the few Philistines still left will be killed,” says the Sovereign LORD.
