Num 32:1-18 Now the people of Reuben and the people of Gad had a very great number of livestock. And they saw the land of Jazer and the land of Gilead, and behold, the place was a place for livestock. So the people of Gad and the people of Reuben came and said to Moses and to Eleazar the priest and to the chiefs of the congregation, “Ataroth, Dibon, Jazer, Nimrah, Heshbon, Elealeh, Sebam, Nebo, and Beon, the land that the LORD struck down before the congregation of Israel, is a land for livestock, and your servants have livestock.” And they said, “If we have found favor in your sight, let this land be given to your servants for a possession. Do not take us across the Jordan.” But Moses said to the people of Gad and to the people of Reuben, “Shall your brothers go to the war while you sit here? Why will you discourage the heart of the people of Israel from going over into the land that the LORD has given them? Your fathers did this, when I sent them from Kadesh-barnea to see the land. For when they went up to the Valley of Eshcol and saw the land, they discouraged the heart of the people of Israel from going into the land that the LORD had given them. And the LORD’s anger was kindled on that day, and he swore, saying, ‘Surely none of the men who came up out of Egypt, from twenty years old and upward, shall see the land that I swore to give to Abraham, to Isaac, and to Jacob, because they have not wholly followed me, none except Caleb the son of Jephunneh the Kenizzite and Joshua the son of Nun, for they have wholly followed the LORD.’ And the LORD’s anger was kindled against Israel, and he made them wander in the wilderness forty years, until all the generation that had done evil in the sight of the LORD was gone. And behold, you have risen in your fathers’ place, a brood of sinful men, to increase still more the fierce anger of the LORD against Israel! For if you turn away from following him, he will again abandon them in the wilderness, and you will destroy all this people.” Then they came near to him and said, “We will build sheepfolds here for our livestock, and cities for our little ones, but we will take up arms, ready to go before the people of Israel, until we have brought them to their place. And our little ones shall live in the fortified cities because of the inhabitants of the land. We will not return to our homes until each of the people of Israel has gained his inheritance.
Num 32:23 But if you will not do so, behold, you have sinned against the LORD, and be sure your sin will find you out.
Here is a proposal made by the Reubenites and Gadites, that the land lately conquered might be allotted to them. Two things common in the world might lead these tribes to make this choice; the lust of the eye, and the pride of life. There was much amiss in the principle they went upon; they consulted their own private convenience more than the public good. Thus to the present time, many seek their own things more than the things of Jesus Christ; and are led by worldly interests and advantages to take up short of the heavenly Canaan. The proposal showed disregard to the land of Canaan, distrust of the Lord’s promise, and unwillingness to encounter the difficulties and dangers of conquering and driving out the inhabitants of that land. Moses is wroth with them. It will becomes any of God’s Israel to sit down unconcerned about the difficult and perilous concerns of their brethren, whether public or personal. He reminds them of the fatal consequences of the unbelief and faint-heartedness of their fathers, when they were, as themselves, just ready to enter Canaan. If men considered as they ought what would be the end of sin, they would be afraid of the beginning of it.
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. (Henry)
