16 Then they came to him, and said, We will make safe places for our cattle here, and towns for our little ones; 17 But we ourselves will be ready armed to go before the children of Israel till we have taken them to their place: but our little ones will be safe in the walled towns against the people of the land. 18 We will not come back to our houses till every one of the children of Israel has come into his heritage. 19 For we will not have our heritage with them on the other side of Jordan and forward; because our heritage has come to us on this side of Jordan to the east. 20 Then Moses said to them, If you will do this, arming yourselves to go before the Lord to the war, 21 Every armed man of you going across Jordan before the Lord till he has overcome and sent in flight all who are against him, 22 And the land is under the rule of the Lord: then after that you may come back, having done no wrong to the Lord and to Israel; and this land will be yours for your heritage before the Lord. 23 But if you do not do this, then you are sinners against the Lord; and you may be certain that your sin will have its reward. 24 So get to work building your towns for your little ones, and safe places for your sheep; and do as you have said. 25 And the children of Gad and the children of Reuben said to Moses, Your servants will do as my lord says. 26 Our little ones, our wives, and our flocks, and all our cattle, will be there in the towns of Gilead; 27 But your servants will go over, every man armed for war, before the Lord to the fight, 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.
