Parallel
Numbers 21:13
Swete's Septuagint · Berean Standard Bible
ἐκεῖθεν ἀπάραντες παρενέβαλον εἰς τὸ πέραν ’ ἐν τῇ ἐρήμῳ, τὸ ἐξέχον ἀπὸ τῶν ὁρίων τῶν Ἀμορραίων· ἔστιν γὰρ Ἀρνῶν ὅρια Μωὰβ ἀνὰ μέσον Μωὰβ καὶ ἀνὰ μέσον τοῦ Ἀμορραίου.
From there they moved on and camped on the other side of the Arnon, in the wilderness that extends into the Amorite territory. Now the Arnon is the border between the Moabites and the Amorites.
