Job 41:23

The flakes of his flesh are joined together: they are firm in themselves; they cannot be moved.

The flakes of his flesh are joined together. They are firm on him. They can't be moved.

The flakes of his flesh are joined together: They are firm upon him; they cannot be moved.

The flakes of his flesh have adhered -- Firm upon him -- it is not moved.

The folds of his flesh are tightly joined; they are firm and immovable.
