Jeremiah 8:17

He proceeds in increasing of their terror: q.d. There will be no appeasing or allaying of their fury by any art or method; therefore represented by the cockatrice, called in Latin regulus, or king of serpents, as putting to flight all other serpents; but by apposition to serpents, showing what kind of serpent they shall be, a sort that cannot be charmed, viz. such an enemy as by no entreaty can be made exorable: see on Isaiah 11:8. LXX. deadly serpents. They shall bite you; they shall afflict you with sore punishments, not only stings in their tails, as scorpions, but in their teeth, whereby they shall devour you, Jeremiah 8:16.
