Numbers 21:13 YLT

¹¹  And they journey from Oboth, and encamp in Ije-Abarim, in the wilderness that 'is' on the front of Moab, at the rising of the sun.

¹²  From thence they have journeyed, and encamp in the valley of Zared.

¹³  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  therefore it is said in a book, 'The wars of Jehovah,' -- 'Waheb in Suphah, And the brooks of Arnon;

¹⁵  And the spring of the brooks, Which turned aside to the dwelling of Ar, And hath leaned to the border of Moab.'
