'Whose' in the Bible

This is a list of the kings who ruled the land that the Israelis conquered, and whose territories they took on the other side of the Jordan River toward the east, from the Arnon River to Mount Hermon, along with the entire eastern Jordan plain.

If you think it's the wrong thing for you to serve the LORD, then choose for yourselves today whom you will serve the gods whom your ancestors served on the other side of the Euphrates River, or the gods of the Amorites in whose territories you are living. But as for me and my household, we will serve the LORD."

since the LORD our God is the one who brought us and our ancestors up from the land of Egypt, from a life of slavery. He did those great things right in front of us, preserving us along the way that we traveled and among all the nations through whose territory we passed.
