(1.) Here is a general description of the country that was given to the two tribes and a half, which Moses gave them, even as Moses gave them, v. 8. The repetition implies a ratification of the grant by Joshua. Moses settled this matter, and, as Moses settled it, so shall it rest; Joshua will not, under any pretence whatsoever, go about to alter it. And a reason is intimated why he would not, because Moses was the servant of the Lord, and acted in this matter by secret direction from him and was faithful as a servant. Here we have, [1.] The fixing of the boundaries of this country, by which they were divided from the neighbouring nations, v. 9, &c. Israel must know their own and keep to it, and may not, under pretence of their being God's peculiar people, encroach upon their neighbours, and invade their rights and properties, to which they had a good and firm title by providence, though not, as Israel, a title by promise. [2.] An exception of one part of this country from Israel's possession, though it was in their grant, namely, the Geshurites and the Maachathites, v. 13. They had not leisure to reduce all the remote and obscure corners of the country in Moses's time, and afterwards they had no mind to it, being easy with what they had. Thus those who are not straitened in God's promises are yet straitened in their own faith, and prayers, and endeavours.
