At this point the history incorporates, why we cannot tell, part of an old song from the "Book of the Wars of Jehovah." "Vaheb in Suphah, And the valleys of Arnon, And the slope of the valleys That inclineth toward the dwelling of Ar, And leaneth upon the border of Moab." The picturesque topography of this chant, the meaning of which as a whole is obscured for us by the first line, may be the sole reason of its quotation. If we read "Vaheb in storm" we have a word-picture of the scene under impressive conditions; and if the storm is that of war the relique may belong to the time of the contest described in ver. 26 when the Amorite chief, crossing Jordan, gained the northern heights and drove the Moabites in confusion across the Arnon toward the stronghold of Ar, some twelve or fifteen miles to the south. Yet another ancient song is connected with a station called Beer, or the Well, some spot in the wilderness north of the Arnon valley. Moses points out the place where water may be found, and as the digging goes on the chant is heard: "Spring up, O well; sing ye unto it: The well which the princes digged, Which the nobles of the people delved, With the sceptre, and with their staves." The seeking of the precious water by rude art in a thirsty valley kindles the mind of some poet of the people. And his song is spirited, with ample recognition of the zeal of the princes who themselves take part in the labour. While they dig he chants, and the people join in the song till the words are fixed in their memory, so as to become part of the traditions of Israel.
