TSK · Numbers 21:23

And Edom said unto him, Thou shalt not pass through me, lest I come out with the sword against thee.

But Sihon king of Heshbon would not let us pass by him; for Jehovah thy God hardened his spirit, and made his heart obstinate, that he might deliver him into thy 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 dwelt at Heshbon, whom Moses and the children of Israel smote, when they came forth out of Egypt.

But Sihon trusted not 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 unto Elealeh, even unto Jahaz have they uttered their voice, from Zoar even unto Horonaim, to Eglath-shelishiyah: for the waters of Nimrim also shall become desolate.
