TSK · Numbers 21:23

Edom said to him, "You shall not pass through me, lest I come out with the sword against you."

But Sihon king of Heshbon would not let us pass by him; for Yahweh your God hardened his spirit, and made his heart obstinate, that he might deliver him into your hand, as at this day.

beyond the Jordan, in the valley over against Beth Peor, in the land of Sihon king of the Amorites, who lived at Heshbon, whom Moses and the children of Israel struck, when they came forth out of Egypt.

But Sihon didn't trust Israel to pass through his border; but Sihon gathered all his people together, and encamped in Jahaz, and fought against Israel.

From the cry of Heshbon even to Elealeh, even to Jahaz have they uttered their voice, from Zoar even to Horonaim, to Eglath Shelishiyah: for the waters of Nimrim also shall become desolate.
