'Reigning' in the Bible

[This happened] {after defeating} Sihon king of the Amorites, who [was] reigning in Heshbon, and Og the king of Bashan, who [was] reigning in Ashtaroth in Edrei.

And Yahweh said to me, 'You should not fear him, for I have given him and all [of] his army and his land into your hand. And [so] you will do to him as you did to Sihon the king of the Amorites, who [was] reigning in Heshbon.'

beyond the Jordan in the valley opposite Beth Peor in the land of Sihon the king of the Amorites, who [was] reigning in Heshbon [and] whom Moses and the {Israelites} defeated {when they came out of Egypt}.
