The book of the wars of the Lord. — Nothing is known about this book. The last days of Moses, as Baumgarten has observed, may have been a suitable time for the commencement of such a work. The history of the journey from Kadesh to the Arboth Moab was not written by Moses until after the defeat of the two kings of the Amorites, and the subjugation of the land on the east of the Jordan.
What he did in the Red Sea... — The original is very obscure. It is probable that some such verb as They conquered (or, subdued) is understood, and that the words may be rendered Vaheb in Suphah and the valleys (by) Arnon, and the bed (or, ravine) of the valleys which inclines towards the dwelling of Ar, and leans upon the border of Moab. Vaheb was probably the name of a town, and Suphah the district in which that town was situated, so called from its reeds and rushes. Some, however, think that Suphah here denotes a storm or hurricane, as in other places. Ar is supposed to be the same as Areopolis.
