21 And Israel sent messengers to Sihon king of the Amorites, saying, 22 Let us pass through thy land; we will not turn into the fields, or into the vineyards; we will not drink water out of the wells; on the king's road will we go until we have passed thy border. 23 But Sihon would not suffer Israel to go through his border; and Sihon gathered all his people, and went out against Israel into the wilderness, and came to Jahaz, and fought against Israel. 24 And Israel smote him with the edge of the sword, and took possession of his land from the Arnon to the Jabbok, even unto the children of Ammon; for the border of the children of Ammon was strong. 25 And Israel took all these cities, and Israel dwelt in all the cities of the Amorites, at Heshbon, and in all its dependent villages. 26 For Heshbon was the city of Sihon the king of the Amorites; and he had fought against the former king of Moab, and had taken all his land out of his hand, even unto the Arnon. 27 Therefore the poets say, Come to Heshbon; let the city of Sihon be built and established. 28 For there went forth fire from Heshbon, a flame from the city of Sihon; It consumed Ar of Moab, the lords of the high places of the Arnon. 29 Woe to thee, Moab! thou art undone, people of Chemosh: He gave his sons that had escaped, and his daughters into captivity to Sihon the king of the Amorites. 30 And we have shot at them; Heshbon is perished even unto Dibon; and we have laid [them] waste even unto Nophah, which reacheth unto Medeba.

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.
