Amos 1:8-10

8I will destroy the king of Ashdod and the one who holds the scepter in Ashkelon. I will turn my hand against Ekron, till the last of the Philistines are dead,” says the Sovereign Lord. 9This is what the Lord says: “For three sins of Tyre, even for four, I will not relent. Because she sold whole communities of captives to Edom, disregarding a treaty of brotherhood, 10I will send fire on the walls of Tyre that will consume her fortresses.”
