16 “Thus says the whole congregation of Yahweh, ‘What trespass is this that you have committed against the God of Israel, to turn away this day from following Yahweh, in that you have built you an altar, to rebel this day against Yahweh? 17 Is the iniquity of Peor too little for us, from which we have not cleansed ourselves to this day, although there came a plague on the congregation of Yahweh, 18 that you must turn away this day from following Yahweh? It will be, seeing that you rebel today against Yahweh, that tomorrow he will be angry with the whole congregation of Israel. 19 However, if the land of your possession is unclean, then pass over to the land of the possession of Yahweh, in which Yahweh’s tabernacle dwells, and take possession among us; but don’t rebel against Yahweh, nor rebel against us, in building an altar other than the altar of Yahweh our God. 20 Didn’t Achan the son of Zerah commit a trespass in the devoted thing, and wrath fell on all the congregation of Israel? That man didn’t perish alone in his iniquity.’”

(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.
