וַיֵּצֵא֩ סִיחֹ֨ן לִקְרָאתֵ֜נוּ ה֧וּא וְכָל־עַמּ֛וֹ לַמִּלְחָמָ֖ה יָֽהְצָה׃
Lalu Sihon beserta seluruh rakyatnya keluar menyongsong kami untuk berperang di Yahas.
Rashi
ויצא סיחן AND SIHON WENT FORTH — He did not send for Og to help him: this serves to teach you that they did not require one another's help, so mighty was each of them.
