'For Us' in the Bible

And it came to pass after the death of Joshua, that the children of Israel asked of Jehovah, saying, Who shall go up for us first against the Canaanites, to fight against them?

And the children of Israel arose, and went up to Beth-el, and asked counsel of God; and they said, Who shall go up for us first to battle against the children of Benjamin? And Jehovah said, Judah'shall go up first.
