'Gates' 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.

For I know your crimes are manyand your sins innumerable.They oppress the righteous, take a bribe,and deprive the poor of justice at the gates.
