Zechariah 9:6

“Do not be glad, O Philistia, all of you, Because the rod that struck you is broken; For from the serpent’s root a viper will come out, And its fruit will be a flying fiery serpent.

That which came as the word of Yahweh to Jeremiah the prophet concerning the Philistines, before Pharaoh struck down Gaza.

“Moreover, what are you to Me, O Tyre, Sidon, and all the regions of Philistia? Are you rendering Me a recompense? But if you do recompense Me, swiftly and speedily I will return your recompense on your head.

“I will also cut off the inhabitant from Ashdod And him who holds the scepter from Ashkelon; I will even turn My hand against Ekron, And the remnant of the Philistines will perish,” Says Lord Yahweh.

For Gaza will be forsaken And Ashkelon a desolation; Ashdod will be driven out at noon, And Ekron will be uprooted.
