Jeremiah 47:1

The word of the Lord that came to Jeremiah, the prophet, against the Philistines, the ancient enemies of the people of Israel on the west, along the shores of the Mediterranean, before that Pharaoh smote Gaza. The exact occasion of this conquest is a matter of conjecture. It may be that Pharaoh-necho took the city after the battle of Megiddo, or that Pharaoh-hophra smote the city after his vain attempt to drive the Chaldeans out of the country. At any rate, Gaza was strong enough after its conquest by Pharaoh to be an object of anxious concern and to demand stern measures on account of its opposition to Jehovah.
