11 Now the children of Israel heard someone say, "Behold, the children of Reuben, the children of Gad, and half the tribe of Manasseh have built an altar on the frontier of the land of Canaan, in the region of the Jordan--on the children of Israel's side." 12 And when the children of Israel heard of it, the whole congregation of the children of Israel gathered together at Shiloh to go to war against them. 13 Then the children of Israel sent Phinehas the son of Eleazar the priest to the children of Reuben, to the children of Gad, and to half the tribe of Manasseh, into the land of Gilead, 14 and with him ten rulers, one ruler each from the chief house of every tribe of Israel; and each one was the head of the house of his father among the divisions of Israel. 15 Then they came to the children of Reuben, to the children of Gad, and to half the tribe of Manasseh, to the land of Gilead, and they spoke with them, saying, 16 "Thus says the whole congregation of the Lord: 'What treachery is this that you have committed against the God of Israel, to turn away this day from following the Lord, in that you have built for yourselves an altar, that you might rebel this day against the Lord? 17 Is the iniquity of Peor not enough for us, from which we are not cleansed until this day, although there was a plague in the congregation of the Lord, 18 but that you must turn away this day from following the Lord? And it shall be, if you rebel today against the Lord, that tomorrow He will be angry with the whole congregation of Israel. 19 Nevertheless, if the land of your possession is unclean, then cross over to the land of the possession of the Lord, where the Lord's tabernacle stands, and take possession among us; but do not rebel against the Lord, nor rebel against us, by building yourselves an altar besides the altar of the Lord our God. 20 Did not Achan the son of Zerah commit a trespass in the accursed thing, and wrath fell on all the congregation of Israel? And that man did not perish alone in his iniquity.' "

21 Then the children of Reuben, the children of Gad, and half the tribe of Manasseh answered and said to the heads of the divisions of Israel: 22 "The Lord God of gods, the Lord God of gods, He knows, and let Israel itself know--if it is in rebellion, or if in treachery against the Lord, do not save us this day. 23 If we have built ourselves an altar to turn from following the Lord, or if to offer on it burnt offerings or grain offerings, or if to offer peace offerings on it, let the Lord Himself require an account. 24 But in fact we have done it for fear, for a reason, saying, 'In time to come your descendants may speak to our descendants, saying, "What have you to do with the Lord God of Israel? 25 For the Lord has made the Jordan a border between you and us, you children of Reuben and children of Gad. You have no part in the Lord." So your descendants would make our descendants cease fearing the Lord.' 26 Therefore we said, 'Let us now prepare to build ourselves an altar, not for burnt offering nor for sacrifice, 27 but that it may be a witness between you and us and our generations after us, that we may perform the service of the Lord before Him with our burnt offerings, with our sacrifices, and with our peace offerings; that your descendants may not say to our descendants in time to come, "You have no part in the Lord." ' 28 Therefore we said that it will be, when they say this to us or to our generations in time to come, that we may say, 'Here is the replica of the altar of the Lord which our fathers made, though not for burnt offerings nor for sacrifices; but it is a witness between you and us.' 29 Far be it from us that we should rebel against the Lord, and turn from following the Lord this day, to build an altar for burnt offerings, for grain offerings, or for sacrifices, besides the altar of the Lord our God which is before His tabernacle."

Commentary on Joshua 22:10-20

(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.

Commentary on Joshua 22:21-29

(Read Joshua 22:21-29)

The tribes took the reproofs of their brethren in good part. With solemnity and meekness they proceeded to give all the satisfaction in their power. Reverence of God is expressed in the form of their appeal. This brief confession of faith would remove their brethren's suspicion that they intended to worship other gods. Let us always speak of God with seriousness, and mention his name with a solemn pause. Those who make appeals to Heaven with a careless "God knows," take his name in vain: it is very unlike this. They express great confidence of their own uprightness in the matter of their appeal. "God knows it," for he is perfectly acquainted with the thoughts and intents of the heart. In every thing we do in religion, it highly concerns us to approve ourselves to God, remembering that he knows the heart. And if our sincerity be known to God, we should study likewise to let others know it by its fruits, especially those who, though they mistake us, show zeal for the glory of God. They disdained the design of which they were suspected to be guilty, and fully explained their true intent in building this altar. Those who have found the comfort and benefit of God's ordinances, cannot but desire to preserve them to their seed, and to use all possible care that their children may be looked upon as having a part in him. Christ is the great Altar that sanctifies every gift; the best evidence of our interest in him is the work of his Spirit in our hearts.
