16 Then they came up to him and said, "We will build sheepfolds here for our flocks, and towns for our little ones, 17 but we will take up arms as a vanguard before the Israelites, until we have brought them to their place. Meanwhile our little ones will stay in the fortified towns because of the inhabitants of the land. 18 We will not return to our homes until all the Israelites have obtained their inheritance. 19 We will not inherit with them on the other side of the Jordan and beyond, because our inheritance has come to us on this side of the Jordan to the east." 20 So Moses said to them, "If you do this-if you take up arms to go before the Lord for the war, 21 and all those of you who bear arms cross the Jordan before the Lord, until he has driven out his enemies from before him 22 and the land is subdued before the Lord-then after that you may return and be free of obligation to the Lord and to Israel, and this land shall be your possession before the Lord. 23 But if you do not do this, you have sinned against the Lord; and be sure your sin will find you out. 24 Build towns for your little ones, and folds for your flocks; but do what you have promised." 25 Then the Gadites and the Reubenites said to Moses, "Your servants will do as my lord commands. 26 Our little ones, our wives, our flocks, and all our livestock shall remain there in the towns of Gilead; 27 but your servants will cross over, everyone armed for war, to do battle for the Lord, just as my lord orders."

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.
