And Og the king of Bashan,.... A country large and fruitful, and the king of it of a gigantic stature, see Psalms 135:11;
for his mercy [endureth] for ever; for this mighty king came out against Israel, and threatened their destruction, and it was of the Lord's mercies they were not consumed by him. And it may be observed, whenever tyrannical princes and oppressors are cut off, it is in mercy to the inhabitants of the earth, and especially to the people of God.
