their rock is not as our ROCK

But Jeshurun grew fat, and kicked: You have grown fat, you are grown thick, you are become sleek; Then he forsook God who made him, Lightly esteemed the Rock of his salvation. 18 Of the Rock that became your father, you are unmindful, Have forgotten God who gave you birth. 28 For they are a nation void of counsel, There is no understanding in them. 29 Oh that they were wise, that they understood this, That they would consider their latter end! 30 How should one chase a thousand, Two put ten thousand to flight, Except their Rock had sold them, Yahweh had delivered them up? 31 For their rock is not as our Rock, Even our enemies themselves being judges.
Deuteronomy 32:3,4,15,18,31
