'Aghast' in the Bible

They will be terrified; pain and anguish will seize them; they'll writhe like a woman in labor. They'll look aghast at one another; and their faces will be ablaze with fear.

For he did not [really] know what to say because they were terrified [and stunned by the miraculous sight].

In fact, so terrifying was the sight, that Moses said, “I am filled with fear and trembling.”
