Job 41:23

The flakes of his flesh are joined together -Margin, “fallings.” The Hebrew word used here means anything “falling,” or “pendulous,” and the reference here is, probably, to the pendulous parts of the flesh of the animal; the flabby parts; the dew-laps. In animals commonly these parts about the neck and belly are soft, pendulous, and contribute little to their strength. The meaning here is, that in the leviathan, instead of being thus flabby and pendulous, they were compact and firm. This is strikingly true of the crocodile.
