16 "The whole community of the Lord demands to know why you are betraying the God of Israel. How could you turn away from the Lord and build an altar for yourselves in rebellion against him? 17 Was our sin at Peor not enough? To this day we are not fully cleansed of it, even after the plague that struck the entire community of the Lord . 18 And yet today you are turning away from following the Lord . If you rebel against the Lord today, he will be angry with all of us tomorrow. 19 "If you need the altar because the land you possess is defiled, then join us in the Lord 's land, where the Tabernacle of the Lord is situated, and share our land with us. But do not rebel against the Lord or against us by building an altar other than the one true altar of the Lord our God. 20 Didn't divine anger fall on the entire community of Israel when Achan, a member of the clan of Zerah, sinned by stealing the things set apart for the Lord ? He was not the only one who died because of 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.
