"Until the LORD have given your brethren rest, as he hath given you, and they also have possessed the land which the LORD your God giveth them: then ye shall return unto the land of your possession, and enjoy it, which Moses the LORD'S servant gave you on this side Jordan toward the sunrising."

It's so easy for me to put my own needs and safety first. I don't want to be selfish, but it's so easy for me to only see things from my point of view when I have to decide how to spend my time. But for God's people, it's important to think in terms of "we" and "us," not "me" and "mine." The Israelites from the east had reached the land God had promised them, but they couldn't stop fighting and move there until all of God's people were safe in their homeland.
