16 They came close to him and said, "All we want to do is build corrals for our livestock and towns for our families. 17 Then we'll take up arms and take the front lines, leading the People of Israel to their place. We'll be able to leave our families behind, secure in fortified towns, safe from those who live in the land. 18 But we won't go back home until every Israelite is in full possession of his inheritance. 19 We won't expect any inheritance west of the Jordan; we are claiming all our inheritance east of the Jordan." 20 Moses said, "If you do what you say, take up arms before God for battle 21 and together go across the Jordan ready, before God, to fight until God has cleaned his enemies out of the land, 22 then when the land is secure you will have fulfilled your duty to God and Israel. Then this land will be yours to keep before God. 23 "But if you don't do what you say, you will be sinning against God; you can be sure that your sin will track you down. 24 So, go ahead. Build towns for your families and corrals for you livestock. Do what you said you'd do." 25 The families of Gad and Reuben told Moses: "We will do as our master commands. 26 Our children and wives, our flocks and herds will stay behind here in the towns of Gilead. 27 But we, every one of us fully armed, will cross the river to fight for God, just as our master has said."

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.
