Numbers 21:23-35

23 aBut Sihon would not allow Israel to pass through his territory. He gathered all his people together and went out against Israel to the wilderness and bcame to Jahaz and fought against Israel. 24 cAnd Israel defeated him with the edge of the sword and took possession of his land from the Arnon to the dJabbok, as far as to the Ammonites, for the border of the Ammonites was strong. 25And Israel took all these cities, and Israel settled in all the cities of the Amorites, in Heshbon, and in all its villages. 26For Heshbon was the city of Sihon the king of the Amorites, who had fought against the former king of Moab and taken all his land out of his hand, as far as the Arnon. 27Therefore the eballad singers say,

Come to fHeshbon, let it be built;
let the city of Sihon be established.
28For gfire came out from hHeshbon,
flame from the city of Sihon.
It devoured iAr of Moab,
and swallowed
Septuagint; Hebrew the lords of
the heights of the Arnon.
29 kWoe to you, O Moab!
You are undone, O people of lChemosh!
He has made his sons fugitives,
and his daughters captives,
to an Amorite king, Sihon.
30So we overthrew them;
Heshbon, as far as mDibon, perished;
and we laid waste as far as Nophah;
fire spread as far as nMedeba.”
Compare Samaritan and Septuagint; Hebrew  and we laid waste as far as Nophah, which is as far as Medeba

King Og Defeated

31Thus Israel lived in the land of the Amorites. 32And Moses sent to spy out pJazer, and they captured its villages and dispossessed the Amorites who were there. 33Then they turned and went up by the way to Bashan. And Og the king of Bashan came out against them, he and all his people, to battle qat Edrei. 34 rBut the Lord said to Moses, “Do not fear him, for I have given him into your hand, and all his people, and his land. And syou shall do to him as you did to Sihon king of the Amorites, who lived at Heshbon.” 35So they defeated him and his sons and all his people, until he had no survivor left. And they possessed his land.

Deuteronomy 2:30-33

30But tSihon the king of uHeshbon would not let us pass by him, for the Lord your God vhardened his spirit and made his heart obstinate, that he might give him into your hand, as he is this day. 31And the Lord said to me, ‘Behold, I have begun to give Sihon and his land over to you. Begin to take possession, that you may occupy his land.’ 32Then wSihon came out against us, he and all his people, to battle at Jahaz. 33And xthe Lord our God gave him over to us, and ywe defeated him and his sons and all his people.

Deuteronomy 3:1-8

The Defeat of King Og

1“Then we turned and went up the way to Bashan. And zOg the king of Bashan came out against us, he and all his people, to battle at aaEdrei. 2But the Lord said to me, ‘Do not fear him, for I have given him and all his people and his land into your hand. And you shall do to him as you did to abSihon the king of the Amorites, who lived at Heshbon.’ 3So the Lord our God gave into our hand Og also, the king of Bashan, and all his people, acand we struck him down until he had no survivor left. 4And we took all his cities at that time—there was not a city that we did not take from them—sixty cities, adthe whole region of Argob, the kingdom of Og in Bashan. 5All these were cities fortified with high walls, gates, and bars, besides very many unwalled villages. 6And aewe devoted them to destruction,
That is, set apart ( devoted) as an offering to the Lord (for destruction); twice in this verse
as we did to Sihon the king of Heshbon, devoting to destruction every agcity, men, women, and children.
7But all the livestock and the spoil of the cities we took as our plunder. 8So we took the land at that time out of the hand of the two kings of the Amorites who were beyond the Jordan, from the Valley of the Arnon to Mount Hermon

for his steadfast love endures forever;
19Sihon, king of the Amorites,
for his steadfast love endures forever;
20and Og, king of Bashan,
for his steadfast love endures forever;
21and gave their land as a heritage,
for his steadfast love endures forever;
