Numbers 21:23-30 And Sichon gives not Yisra El to pass through his border: but Sichon gathers all his people together and goes and confronts Yisra El in the wilderness: and he comes to Yahsah who fights Yisra El:

ECB⁽ⁱ⁾ ²³ And Sichon gives not Yisra El to pass through his border: but Sichon gathers all his people together and goes and confronts Yisra El in the wilderness: and he comes to Yahsah who fights Yisra El: ²⁴ and Yisra El smites him with the mouth of the sword and possesses his land from Arnon to Yabboq to the sons of Ammon: for the border of the sons of Ammon is strong. ²⁵ And Yisra El takes all these cities: and Yisra El settles in all the cities of the Emoriy, in Heshbon and in all the daughters thereof. ²⁶ For Heshbon is a city of Sichon the sovereign of the Emoriy, who fought the head sovereign of Moab and takes all his land from his hand, to Arnon. ²⁷ So they who proverbialize say, Come into Heshbon, build the city of Sichon and prepare: ²⁸ for there a fire goes from Heshbon a flame from the city of Sichon: it consumes Ar of Moab and the masters of the bamahs of Arnon. ²⁹ Woe to you, Moab! You destruct, O people of Kemosh! He gives his sons and his daughters who escape to captivity to Sichon sovereign of the Emoriy. ³⁰ And we shoot them! Heshbon destructs even to Dibon and we desolate them from Nophach to Medeba.
