21 Then Israel sent messengers to Sihon king of the Amorites, saying, 22 "Let me pass through your land. We will not turn aside into fields or vineyards; we will not drink water from wells. We will go by the King's Highway until we have passed through your territory." 23 But Sihon would not allow Israel to pass through his territory. So Sihon gathered all his people together and went out against Israel in the wilderness, and he came to Jahaz and fought against Israel. 24 Then Israel defeated him with the edge of the sword, and took possession of his land from the Arnon to the Jabbok, as far as the people of Ammon; for the border of the people of Ammon was fortified. 25 So Israel took all these cities, and Israel dwelt in all the cities of the Amorites, in Heshbon and in all its villages. 26 For Heshbon was the city of Sihon king of the Amorites, who had fought against the former king of Moab, and had taken all his land from his hand as far as the Arnon. 27 Therefore those who speak in proverbs say: "Come to Heshbon, let it be built; Let the city of Sihon be repaired. 28 "For fire went out from Heshbon, A flame from the city of Sihon; It consumed Ar of Moab, The lords of the heights of the Arnon. 29 Woe to you, Moab! You have perished, O people of Chemosh! He has given his sons as fugitives, And his daughters into captivity, To Sihon king of the Amorites. 30 "But we have shot at them; Heshbon has perished as far as Dibon. Then we laid waste as far as Nophah, Which reaches to Medeba."
31 Thus Israel dwelt in the land of the Amorites. 32 Then Moses sent to spy out Jazer; and they took its villages and drove out the Amorites who were there. 33 And they turned and went up by the way to Bashan. So Og king of Bashan went out against them, he and all his people, to battle at Edrei. 34 Then the Lord said to Moses, "Do not fear him, for I have delivered him into your hand, with all his people and his land; and you shall do to him as you did to Sihon king of the Amorites, who dwelt at Heshbon." 35 So they defeated him, his sons, and all his people, until there was no survivor left him; and they took possession of his land.

Commentary on Numbers 21:21-35
(Read Numbers 21:21-35)
Sihon went with his forces against Israel, out of his own borders, without provocation, and so ran upon his own ruin. The enemies of God's church often perish by the counsels they think most wisely taken. Og, king of Bashan, instead of being warned by the fate of his neighbours, to make peace with Israel, makes war with them, which proves in like manner his destruction. Wicked men do their utmost to secure themselves and their possessions against the judgments of God; but all in vain, when the day comes on which they must fall. God gave Israel success, while Moses was with them, that he might see the beginning of the glorious work, though he must not live to see it finished. This was, in comparison, but as the day of small things, yet it was an earnest of great things. We must prepare for fresh conflicts and enemies. We must make no peace or truce with the powers of darkness, nor even treat with them; nor should we expect any pause in our contest. But, trusting in God, and obeying his commands, we shall be more than conquerors over every enemy.
