Numbers 21:33

Og, the king of the most fertile country of Basan, was of gigantic stature, Deuteronomy iii. 11. The Rabbins relate many fables concerning him. — Edrai was 15 miles to the north of the torrent Jeboc, (Calmet) which was the southern extremity of this territory. (Haydock)

II. Og king of Bashan, instead of being warned by the fate of his neighbours to make peace with Israel, is instigated by it to make war with them, which proves in like manner to be his destruction. Og was also an Amorite, and therefore perhaps thought himself better able to deal with Israel than his neighbours were, and more likely to prevail, because of his own gigantic strength and stature, which Moses takes notice of, Deut 3 11, where he gives a more full account of this story. Here observe, 1. That the Amorite begins the war (v. 33): He went out to battle against Israel. His country was very rich and pleasant. Bashan was famous for the best timber (witness the oaks of Bashan), and the best breed of cattle, witness the bulls and kine of Bashan, and the lambs and rams of that country, which are celebrated, Deut 32 14. Wicked men do their utmost to secure themselves and their possessions against the judgments of God, but all in vain, when their day comes, on which they must fall. 2. That God interests himself in the cause, bids Israel not to fear this threatening force, and promises a complete victory: "I have delivered him into thy hand (v. 34); the thing is as good as done already, it is all thy own, enter and take possession." Giants are but worms before God's power. 3. That Israel is more than a conqueror, not only routs the enemies' army, but gains the enemies' country, which afterwards was part of the inheritance of the two tribes and a half that were first seated on the other side Jordan. God gave Israel these successes, while Moses was yet with them, both for his comfort (that he might see the beginning of that glorious work, which he must not live to see the finishing of) and for the encouragement of the people in the war of Canaan under Joshua. Though this was to them in comparison but as the day of small things, yet it was an earnest of great things.

Verses 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.
