Verse 16. - Trespass. The Hebrew word signifies to act deceitfully or faithlessly. It was an act of ingratitude towards the God who had established them in the good land in which they now found themselves. Such ingratitude and desertion of God was equivalent to rebellion, the term used immediately afterwards. The embassy clearly assumed that the fault had been committed, and that it would be necessary to proceed to extremities. Yet, deeply moved as they were, they did not refuse to listen to reason, and rejoiced that it was not necessary to inflict the fearful vengeance which otherwise would have been their duty. How great a contrast is this to the readiness, nay, even the eagerness, which many owning the Christian name have displayed to destroy the body, and the soul also, if that were possible, of their brethren in Christ, who have been overtaken, or have been supposed to be overtaken, in a similar fault!

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, Le 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.Thus saith the whole congregation of the Lord,.... By whom they were sent, and whom they represented; and they do not call them the congregation of Israel, but of the Lord, because it was not on a civil but religious account they were come, and not to plead their own cause, but the cause of God; and not so much to show a concern for their own honour and interest as for the glory of God:

what trespass is this that ye have committed against the God of Israel; they took it for granted that they had committed a sin, and that so great, they were not able to express the greatness of it in all its aggravated circumstances, and plainly suggest it was idolatry; which was too premature, when as yet they had not inquired into it; but their zeal for God, and his honour, hurried them into this hasty step:

to turn away this day from following the Lord; they intimate, that they had begun a revolt from the worship of God, which is aggravated by their falling into it so soon, having received so many favours from God, and had so lately seen such wonderful appearances of his power and goodness, and had just had such excellent instructions, exhortations, and cautions given them by Joshua, when he dismissed them:

in that ye have built you an altar; which they supposed was to offer sacrifices upon; whereas there was to be but one altar, and that in the place which the Lord should choose to put his name in, and which he had now chosen, where all sacrifices were to be brought and offered up; see Exodus 20:24,

that ye might rebel this day against the Lord? against the commandment of the Lord expressed in the places referred to, which they charge with rebellion against himself, a very high and heavy charge indeed! but they should first have inquired whether they were guilty of the trespass, or with what view they had built the altar, whether for sacrifice, or for some other use; but they took it for granted it was for sacrifice.
