21 And the children of Reuben and the children of Gad and the half tribe of Manasseh answered and said to the heads of the thousands of Israel, 22 The God of gods, Jehovah, the God of gods, Jehovah, he knoweth, and Israel he shall know [it]; if it is in rebellion, or if in trespass against Jehovah,—save us not this day! 23 —that we have built for ourselves an altar to turn from following Jehovah, and if it is to offer up burnt-offering and oblation on it, and if to offer peace-offerings thereon, let Jehovah himself require it [from us]; 24 and if we have not done it from fear of this thing, saying, In future your children will speak to our children, saying, What have ye to do with Jehovah the God of Israel? 25 Jehovah hath made the Jordan a border between us and you, ye children of Reuben and children of Gad, ye have no portion in Jehovah! And so shall your children make our children cease from fearing Jehovah. 26 And we said, Let us now set to work to build an altar, not for burnt-offering, nor for sacrifice, 27 but to be a witness between us and you, and between our generations after us, that we might do service to Jehovah before him with our burnt-offerings, and with our sacrifices, and with our peace-offerings; that your children may not say to our children in future, Ye have no portion in Jehovah. 28 And we said, If it shall be that in future they so say to us and to our generations, we will say, Behold the pattern of the altar of Jehovah which our fathers made, not for burnt-offering, nor for sacrifice, but as a witness between us and you. 29 Far be it from us that we should rebel against Jehovah, and turn this day from following Jehovah, in building an altar for burnt-offering, for oblation, and for sacrifice, besides the altar of Jehovah our God that is before his tabernacle.

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.
