16 And they came near unto him, and said, We will build sheepfolds here for our cattle, and cities for our little ones: 17 but we ourselves will be ready armed to go before the children of Israel, until we have brought them unto their place: and our little ones shall dwell in the fortified cities because of the inhabitants of the land. 18 We will not return unto our houses, until the children of Israel have inherited every man his inheritance. 19 For we will not inherit with them on the other side of the Jordan, and forward; because our inheritance is fallen to us on this side of the Jordan eastward. 20 And Moses said unto them, If ye will do this thing, if ye will arm yourselves to go before Jehovah to the war, 21 and every armed man of you will pass over the Jordan before Jehovah, until he hath driven out his enemies from before him, 22 and the land is subdued before Jehovah; then afterward ye shall return, and be guiltless towards Jehovah, and towards Israel; and this land shall be unto you for a possession before Jehovah. 23 But if ye will not do so, behold, ye have sinned against Jehovah; and be sure your sin will find you out. 24 Build you cities for your little ones, and folds for your sheep; and do that which hath proceeded out of your mouth. 25 And the children of Gad and the children of Reuben spake unto Moses, saying, Thy servants will do as my lord commandeth. 26 Our little ones, our wives, our flocks, and all our cattle, shall be there in the cities of Gilead; 27 but thy servants will pass over, every man that is armed for war, before Jehovah to battle, as my lord saith.

Commentary on Numbers 32:16-27

(Read Numbers 32:16-27)

Here is the good effect of plain dealing. Moses, by showing their sin, and the danger of it, brought them to their duty, without murmuring or disputing. All men ought to consider the interests of others as well as their own; the law of love requires us to labour, venture, or suffer for each other as there may be occasion. They propose that their men of war should go ready armed before the children of Israel into the land of Canaan, and that they should not return till the conquest of Canaan was ended. Moses grants their request, but he warns them of the danger of breaking their word. If you fail, you sin against the Lord, and not against your brethren only; God will certainly reckon with you for it. Be sure your sin will find you out. Sin will surely find out the sinner sooner or later. It concerns us now to find our sins out, that we may repent of them, and forsake them, lest they find us out to our ruin.
