Numbers 21
13 Ref From thence they have journeyed, and encamp beyond Arnon, which `is' in the wilderness which is coming out of the border of the Amorite, for Arnon `is' the border of Moab, between Moab and the Amorite;
14 Ref therefore it is said in a book, `The wars of Jehovah,' -- `Waheb in Suphah, And the brooks of Arnon;
15 Ref And the spring of the brooks, Which turned aside to the dwelling of Ar, And hath leaned to the border of Moab.'
