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.For the Lord hath made Jordan a border between us and you,.... And by it separated them from them, as if they were a distinct people; not that this was really the case, but so they feared it would be represented in time to come; for though Jordan was the border of the land of Canaan, strictly so called, eastward, Numbers 34:12; yet it did not exclude the land of the two tribes and a half from being part of the land of promise; for the Amorites, which before inhabited it, and were driven out of it, were Canaanites, and were one part of the people, whose land the Lord promised to Abraham, Genesis 15:18,

ye children of Reuben, and children of Gad, have no part in the Lord; in his covenant and promises, in his worship, word, and ordinances; these are things you have nothing to do with, being separated from us his peculiar people; or "have no part in the Word of the Lord", as the Targum, the promised Messiah, being without, or separated from him, as the Gentiles are said to be, Ephesians 2:12,

so shall your children make our children cease from fearing the Lord; from worshipping the Lord, the fear of the Lord being often put for the whole worship of God, external and internal, Ecclesiastes 12:13; by behaving in the above manner towards them, they would be the cause and occasion of their apostasy from the true God, and it would be in effect to say to them, "go, serve other gods", 1 Samuel 26:19.
