The words, "said I," are not in the Hebrew. The words "rise up, and get you over the brook Zered" (Numbers 21:12 note) connect themselves with Deuteronomy 2:9, and form the conclusion of what God said to Moses.

Now rise up, said I, and get you over the brook Zered,.... It is called the valley of Zered, Numbers 21:12, the word used signifying both a valley and a brook; and it is very probable there were both a valley and a brook of the same name; it must be near Dibongad, since in one place it is said the Israelites came from Ijim and pitched in Zered; and in another place that they came from thence, and pitched in Dibongad, Numbers 21:11 and

For this reason Israel was to remove from the desert of Moab (i.e., the desert which bounded Moabitis on the east), and to cross over the brook Zered, to advance against the country of the Amorites (see at Numbers 21:12-13). This occurred thirty-eight years after the condemnation of the people at Kadesh (Numbers 14:23, Numbers 14:29), when the generation rejected by God had entirely died out (תּמם, to be all gone, to disappear), so that not one of them saw the promised land. They did not all die a natural death, however, but "the hand of the Lord was against them to destroy them" (המם, lit., to throw into confusion, then used with special reference to the terrors with which Jehovah destroyed His enemies; Exodus 14:24; Exodus 23:27, etc.), sc., by extraordinary judgments (as in Numbers 16:35; Numbers 18:1; Numbers 21:6; Numbers 25:9).

Now rise up, said I, and get you over the brook Zered. And we went over the brook Zered.

13. Now rise up, and get you over the brook Zered-The southern border of Moab, Zered ("woody"), now Wady Ahsy, separates the modern district of Kerak from Jebal, and, indeed, forms a natural division of the country between the north and south. Ar, called in later times Rabbah, was the capital of Moab and situated twenty-five miles south of the Arnon on the banks of a small but shady stream, the Beni Hamed. It is here mentioned as representative of the country dependent on it, a rich and well-cultivated country, as appears from the numerous ruins of cities, as well as from the traces of tillage still visible on the fields.

2:8-23 We have the origin of the Moabites, Edomites, and Ammonites. Moses also gives an instance older than any of these; the Caphtorims drove the Avims out of their country. These revolutions show what uncertain things wordly possessions are. It was so of old, and ever will be so. Families decline, and from them estates are transferred to families that increase; so little continuance is there in these things. This is recorded to encourage the children of Israel. If the providence of God has done this for Moabites and Ammonites, much more would his promise do it for Israel, his peculiar people. Cautions are given not to meddle with Moabites and Ammonites. Even wicked men must not be wronged. God gives and preserves outward blessings to wicked men; these are not the best things, he has better in store for his own children.
