16 Thus saith the whole congregation of Jehovah, What trespass is this that ye have committed against the God of Israel, to turn away this day from following Jehovah, in that ye have builded you an altar, to rebel this day against Jehovah? 17 Is the iniquity of Peor too little for us, from which we have not cleansed ourselves unto this day, although there came a plague upon the congregation of Jehovah, 18 that ye must turn away this day from following Jehovah? and it will be, seeing ye rebel to-day against Jehovah, that to-morrow he will be wroth with the whole congregation of Israel. 19 Howbeit, if the land of your possession be unclean, then pass ye over unto the land of the possession of Jehovah, wherein Jehovah's tabernacle dwelleth, and take possession among us: but rebel not against Jehovah, nor rebel against us, in building you an altar besides the altar of Jehovah our God. 20 Did not Achan the son of Zerah commit a trespass in the devoted thing, and wrath fell upon all the congregation of Israel? and that man perished not 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.
