dread: fear laid on a creature that drains its will to stand and fight
This is the naming word of a small family built on one picture: something breaking. What it names is not a mood a creature works itself into but a dread laid on it from outside, the kind that takes away the will to hold its ground.
Both places it appears turn on power over animals. After the flood God puts the dread of humans on every living thing, so the fear itself is handed over as part of a grant of authority. In Job the great sea creature is described as the one thing made without it, and that absence is the point: nothing can lay this dread on it, which is why a speech about the creature turns into a speech about its Maker.
What English "dread" misses is the family connection. The verb this word belongs with (חָתַת) is used of bows that snap and of nations broken past repair, so the dread named here is fear with breakage inside it: not a shiver, but a creature's resistance giving way.
