Numbers 21:14-15

¹⁴Wherefore it is said in the book of battles of the Lord, As he did in the Red Sea, so he shall do in the strands of (the) Arnon; (And so it is said in the Book of the Battles of the Lord, As he did at the Red Sea, so he also did at the Arnon River,)

¹⁵the hard rocks of the strands were bowed down, that they shall rest in Ar, or abide there, and should lie in the coasts of Moabites. (and from the cliffs of the river, down to the city of Ar, that sitteth on the border of Moab.)
