16 They came near to him, and said, “We will build sheepfolds here for our livestock, 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 to their place: and our little ones shall dwell in the fortified cities because of the inhabitants of the land. 18 We will not return to 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 Moses said to them, “If you will do this thing, if you will arm yourselves to go before Yahweh to the war, 21 and every armed man of you will pass over the Jordan before Yahweh, until he has driven out his enemies from before him, 22 and the land is subdued before Yahweh; then afterward you shall return, and be guiltless towards Yahweh, and towards Israel; and this land shall be to you for a possession before Yahweh. 23 “But if you will not do so, behold, you have sinned against Yahweh; and be sure your sin will find you out. 24 Build cities for your little ones, and folds for your sheep; and do that which has proceeded out of your mouth.” 25 The children of Gad and the children of Reuben spoke to Moses, saying, “Your servants will do as my lord commands. 26 Our little ones, our wives, our flocks, and all our livestock, shall be there in the cities of Gilead; 27 but your servants will pass over, every man who is armed for war, before Yahweh to battle, as my lord says.”

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.
