Deuteronomy 32:15

But Jeshurun grew fat and kicked— becoming fat, bloated, and gorged. He abandoned the God who made him and scorned the Rock of his salvation.

Note Jeshurun means the upright one, a term of endearment for Israel.

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.

But Jeshurun waxed fat, and kicked: Thou art waxed fat, thou art grown thick, thou art become sleek; Then he forsook God who made him, And lightly esteemed the Rock of his salvation.
