Moses said to the Gadites and the Reubenites, “Must your brothers go to war while you remain here?

Only do not rebel against the Lord, and do not fear the people of the land, for they are bread for us. Their protection has turned aside from them, but the Lord is with us. Do not fear them!”

“Any of you who has killed anyone or touched any of the dead, remain outside the camp for seven days; purify yourselves and your captives on the third day, and on the seventh day.
