'For Us' in the Bible

"Lord GOD," Joshua asked, "Why have you brought this people across the Jordan River? To hand us over to the Amorites so we'll be destroyed? Wouldn't it have been better for us to be content to settle on the other side of the Jordan?

The descendants of Joseph replied, "The hill country isn't sufficient for us, but all the Canaanites who live on the plain have iron chariots, both those in Beth-shean and its villages as well as the inhabitants of the Jezreel Valley."

Isn't the evil that happened at Peor enough for us, from which we have yet to be completely cleansed even to this point, and because of which a plague came upon the community of the LORD?

and then told all of the people, "Look! This stone will testify for us, because it has heard everything that the LORD has spoken to us. So it will stand as a witness against you in the event that you deny your God."
