Numbers 21:6

Fiery serpents - השרפים הנחשים hannechashim hasseraphim . I have observed before, on Gen. iii., that it is difficult to assign a name to the creature termed in Hebrew nachash ; it has different significations, but its meaning here and in Gen. iii. is most difficult to be ascertained. Seraphim is one of the orders of angelic beings, Isaiah 6:2 , Isaiah 6:6 ; but as it comes from the root שרף saraph , which signifies to burn, it has been translated fiery in the text. It is likely that St. Paul alludes to the seraphim, Hebrews 1:7 ; : Who maketh his angels spirits, and his ministers a Flame Of Fire. The animals mentioned here by Moses may have been called fiery because of the heat, violent inflammation, and thirst, occasioned by their bite; and consequently, if serpents, they were of the prester or dipsas species, whose bite, especially that of the former, occasioned a violent inflammation through the whole body, and a fiery appearance of the countenance. The poet Lucan has well expressed this terrible effect of the bite of the prester, and also of the dipsas, in the ninth book of his Pharsalia, which, for the sake of those who may not have the work at hand, I shall here insert.

Of the mortal effects of the bite of the dipsas in the deserts of Libya he gives the following description: -

" Signiferum juvenem Tyrrheni sanguinis Aulum

Torta caput retro dipsas calcata momordit.

Vix dolor aut sensus dentis fuit: ipsaque laeti

Frons caret invidia: nec quidquam plaga minatur.

Ecce subit virus tacitum, carpitque medullas

Ignis edax, calidaque incendit viscera tabe.

Ebibit humorem circum vitalia fusum

Pestis, et in sicco linguam torrere palato

Coepit: defessos iret qui sudor in artus

Non fuit, atque oculos lacrymarum vena refugit."
