Numbers 21:23

וְלֹא־נָתַ֨ן סִיחֹ֣ן אֶת־יִשְׂרָאֵל֮ עֲבֹ֣ר בִּגְבֻלוֹ֒ וַיֶּאֱסֹ֨ף סִיחֹ֜ן אֶת־כָּל־עַמּ֗וֹ וַיֵּצֵ֞א לִקְרַ֤את יִשְׂרָאֵל֙ הַמִּדְבָּ֔רָה וַיָּבֹ֖א יָ֑הְצָה וַיִּלָּ֖חֶם בְּיִשְׂרָאֵֽל׃

καὶ οὐκ ἔδωκεν Σηὼν τῷ Ἰσραὴλ παρελθεῖν διὰ τῶν ὁρίων αὐτοῦ· καὶ συνήγαγεν Σηὼν πάντα τὸν λαὸν αὐτοῦ, καὶ ἐξῆλθεν παρατάξασθαι Ἰσραὴλ εἰς τὴν ἔρημον· καὶ ἦλθεν εἰς Εἴσσα, καὶ παρετάξατο τῷ Ἰσραήλ.

Mas Sehón no dejó pasar á Israel por su término: antes juntó Sehón todo su pueblo, y salió contra Israel en el desierto: y vino á Jahaz, y peleó contra Israel.

But Sihon would not let Israel pass through his territory. Instead, he gathered his whole army and went out to confront Israel in the wilderness. When he came to Jahaz, he fought against Israel.
