Deuteronomy 32:15

So Jacob ate and was filled, and the beloved one kicked; he grew fat, he became thick and broad: then he forsook the God that made him, and departed from God his Saviour.

But Jeshurun waxed fat, and kicked: thou art waxen fat, thou art grown thick, thou art covered with fatness; then he forsook God which made him, and lightly esteemed the Rock of his salvation.

But Jeshurun grew fat, and kicked. You have grown fat. You have grown thick. You have become sleek. Then he abandoned God who made him, and rejected the Rock of his salvation.
