'Ruler' in the Bible

I will break down the gates of Damascus.I will cut off the ruler from the Valley of Aven,and the one who wields the scepter from Beth-eden.The people of Aram will be exiled to Kir.The Lord has spoken.

I will cut off the ruler from Ashdod,and the one who wields the scepter from Ashkelon.I will also turn My hand against Ekron,and the remainder of the Philistines will perish.The Lord God has spoken.
