John Trapp on Jeremiah 8:17

Ver. 17. Behold I will ſend Serpents, Cockatrices] i. e. Chaldees, no leſſe virulent then ſerpents, as violent as horſes. Serpentum tot ſunt venena quot genera, tot pernicies quot species, tot dolores quot colores, ſaith an Ancient: Serpents are of ſeveral ſorts,Iſidor. lib. 12. cap. 2. but all poiſonful and pernicious. The Baſilisk or Cockatrice here inſtanced (the worſt ſort of ſerpents, ſay the Septuagint here) goeth not upon the belly as other ſerpents: but erect from the middle part, and doth ſo infect the aire, that by the peſtilent breath coming therefrom, fruits are killed, and men being but lookt upon by it, and birds flying over it: ſtones alſo are broken thereby, and all other ſerpents put to flight.

Dlod. Piſc. And they ſhall bite you] There is an elegancy in the original.
