'Districts' in the Bible

This is the land that remains:All the districts of the Philistines and the Geshurites:

Then he said to the whole assembly of Israel, “If it seems good to you, and if this is from the Lord our God, let us spread out and send the message to the rest of our relatives in all the districts of Israel, including the priests and Levites in their cities with pasturelands, that they should gather together with us.
