TSK · Numbers 21:23

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

But Sihon king of Heshbon would not let us pass by him: for the LORD thy God hardened his spirit, and made his heart obstinate, that he might deliver him into thy hand, as [appeareth] this day.

On this side Jordan, in the valley over against Bethpeor, in the land of Sihon king of the Amorites, who dwelt at Heshbon, whom Moses and the children of Israel smote, after they were come forth out of Egypt:

But Sihon trusted not Israel to pass through his coast: but Sihon gathered all his people together, and pitched in Jahaz, and fought against Israel.

From the cry of Heshbon [even] unto Elealeh, [and even] unto Jahaz, have they uttered their voice, from Zoar [even] unto Horonaim, [as] an heifer of three years old: for the waters also of Nimrim shall be desolate.
