And be astonished at the terror of those things which thy eyes shall see:

and thou hast been mad, because of the sight of thine eyes which thou dost see.

So that the things which your eyes have to see will send you out of your minds.

And may you be stupefied at the terror of the things your eyes will see.

Et obstupesces propter ea quae videbunt oculi tui.

So that thou shalt be mad, for the sight of thine eyes that thou shall see. On account of the shocking things seen by them, their dreadful calamities, oppressions, and persecutions, such as before related; not only violent diseases on their bodies, which were grievous to behold, as well as their pains were intolerable, and made them mad; but to be deprived of a betrothed wife, a newly built house, and a newly planted vineyard; to have an ox slain, and an ass taken away by their enemies, and their sheep given to them before their eyes; to have their sons and daughters taken from them, and brought up in another religion, and to be stripped of their substance; these have made them stark mad, insomuch that they have sometimes destroyed themselves and their families. In Germany, in their rage and madness, they burnt a city and themselves in it; and, in the same country, being summoned by an edict to change their religion, or to be burnt, they agreed to meet together in a certain house, and destroy one another; and first parents killed their children, and husbands their wives, and then killed themselves; leaving only one person to be their doorkeeper, who finished the tragedy by destroying himself, as their own historian relates (m). Other stories of the like kind are reported of them, and some such facts as done in our own nation (n).

Thou shalt be mad for the sight of thine eyes - Quite put out of the possession of their own souls; quite bereaved of all comfort and hope, and abandoned to utter despair. They that walk by sight, and not by faith, are in danger of losing reason itself, when all about them looks frightful; and their condition is bad indeed, who are mad for the sight of their eyes.
