The flakes of his flesh are joined together. Even the softer muscles, and parts which in most animals are yielding and flabby, in the crocodile are bound up, and, as it were, soldered together (comp.
Job 41:17). They are firm in themselves; rather, they are firm upon him; literally, fused upon him, like detached pieces of metal, which are melted one into another. They cannot be moved. His whole body is so firmly compacted together that it is all one piece; the separate parts cannot be moved separately.
One result is that the crocodile has great difficulty in turning.
