10 Now when they came to the country by Jordan in the land of Canaan, the children of Reuben and the children of Gad and the half-tribe of Manasseh put up there, by Jordan, a great altar, seen from far. 11 And news came to the children of Israel, See, the children of Reuben and the children of Gad and the half-tribe of Manasseh have put up an altar opposite the land of Canaan, in the country by Jordan on the side which is Israel's. 12 Then all the meeting of the children of Israel, hearing this, came together at Shiloh to go up against them to war. 13 And the children of Israel sent Phinehas, the son of Eleazar the priest, to the children of Reuben and the children of Gad and the half-tribe of Manasseh, to the land of Gilead, 14 And with him they sent ten chiefs, one for every tribe of the children of Israel, every one of them the head of his house among the families of Israel. 15 And they came to the children of Reuben and the children of Gad and the half-tribe of Manasseh, to the land of Gilead, and said to them, 16 This is what all the meeting of the people of the Lord has said, What is this wrong which you have done against the God of Israel, turning back this day from the Lord and building an altar for yourselves, and being false to the Lord? 17 Was not the sin of Baal-peor great enough, from which we are not clear even to this day, though punishment came on the people of the Lord, 18 That now you are turned back from the Lord? and, because you are false to him today, tomorrow his wrath will be let loose on all the people of Israel. 19 But if the land you now have is unclean, come over into the Lord's land where his House is, and take up your heritage among us: but do not be false to the Lord and to us by building yourselves an altar in addition to the altar of the Lord our God. 20 Did not Achan, the son of Zerah, do wrong about the cursed thing, causing wrath to come on all the people of Israel? And not on him only came the punishment of death.

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.
