16 "The entire congregation of God wants to know: What is this violation against the God of Israel that you have committed, turning your back on God and building your own altar - a blatant act of rebellion against God? 17 Wasn't the crime of Peor enough for us? Why, to this day we aren't rid of it, still living with the fallout of the plague on the congregation of God! 18 Look at you - turning your back on God! If you rebel against God today, tomorrow he'll vent his anger on all of us, the entire congregation of Israel. 19 "If you think the land of your possession isn't holy enough but somehow contaminated, come back over to God's possession, where God's Dwelling is set up, and take your land there, but don't rebel against God. And don't rebel against us by building your own altar apart from the Altar of our God. 20 When Achan son of Zerah violated the holy curse, didn't anger fall on the whole congregation of Israel? He wasn't the only one to die for his sin."

(Read Joshua 22:10-20)
Here is the care of the separated tribes to keep their hold of Canaan's religion. At first sight it seemed a design to set up an altar against the altar at Shiloh. God is jealous for his own institutions; we should be so too, and afraid of every thing that looks like, or leads to idolatry. Corruptions in religion are best dealt with at first. But their prudence in following up this zealous resolution is no less commendable. Many an unhappy strife would be prevented, or soon made up, by inquiries into the matter of the offence. The remembrance of great sins committed formerly, should engage us to stand on our guard against the beginnings of sin; for the way of sin is down-hill. We are all concerned to reprove our neighbour when he does amiss, lest we suffer sin upon him, Leviticus 19:17. The offer made that they should be welcome to come to the land where the Lord's tabernacle was, and settle there, was in the spirit of true Israelites.
