'For Us' in the Bible

And he said, Do not go from us; for you will be eyes for us, guiding us to the right places in the waste land to put up our tents.

And if you come with us, we will give you a part in whatever good the Lord does for us.

Why is the Lord taking us into this land to come to our death by the sword? Our wives and our little ones will get into strange hands: would it not be better for us to go back to Egypt?
