The Toxicoa is very plentiful in Northern Africa, Palestine, Syria, and the neighbouring countries, and, as it is exceedingly active, is held in some dread by the natives. The Toxicoa is closely allied to the dreaded Horatta-pam snake of India (Echis carinata).
The old Hebraists can make nothing of the word, but it is not unlikely that a further and fuller investigation of the ophiology of Northern Africa may succeed where mere scholarship, unallied with zoological knowledge, has failed.
The next word is acshub (pronounced ăk-shoob). It only occurs in one passage, namely Ps. cxl. 3: "They have sharpened their tongues like a serpent (nachash); adder's (acshub) poison is under their lips." The precise species represented by this word is unknown. Buxtorf, however, explains the word as the Spitter, "illud genus quod venenum procul exspuit." Now, if we accept this derivation, we must take the word acshub as a synonym for pethen. We have already identified the Pethen with the Naja haje, a snake which has the power of expelling the poison to some distance, when it is out of reach of its enemy. Whether the snake really intends to eject the poison, or whether it is merely flung from the hollow fangs by the force of the suddenly-checked stroke, is uncertain. That the Haje cobra can expel its poison is an acknowledged fact, and the Dutch colonists of the Cape have been so familiarly acquainted with this habit, that they have called this reptile by the name of Spuugh-Slange, or Spitting Snake, a name which, if we accept Buxtorf's etymology, is precisely equivalent to the word acshub.
Another name of a poisonous snake occurs several times in the Old Testament. The word is tsepha, or tsiphôni, and it is sometimes translated as Adder, and sometimes as Cockatrice. The word is rendered as Adder in Prov. xxiii. 32, where it is said that wine "biteth like a serpent, and stingeth like an adder." Even in this case, however, the word is rendered as Cockatrice in the marginal translation.
It is found three times in the Book of Isaiah. Ch. xi. 8: "The weaned child shall put his hand on the cockatrice' den." Also, ch. xiv. 29: "Rejoice not thou, whole Palestina, because the rod of him that smote thee is broken: for out of the serpent's (nachash) nest shall come forth a cockatrice (tsepha), and his fruit shall be a fiery flying serpent." The same word occurs again in ch. lix. 5: "They hatch cockatrice' eggs." In the prophet Jeremiah we again find the word: "For, behold, I will send serpents, cockatrices among you, which will not be charmed, and they shall bite you, saith the Lord."
This last passage gives us a little, but not much, assistance in identifying the Tsepha. We learn by it that the Tsepha was one of the serpents that were not subject to charmers, and so we are able to say that it was neither the cobra, which we have identified with the Pethen of Scripture, nor the Cerastes or Horned Snake, which has been shown to be the Shephiphon. Our evidence is therefore only of a negative character, and the only positive evidence is that which may be inferred from the passage in Isa. xiv. 29, where the Tsepha is evidently thought to be more venomous than the ordinary serpent or Nachash.
Mr. Tristram suggests that the Tsepha of Scripture may possibly be the Yellow Viper (Daboia xanthica), which is one of the largest and most venomous of the poisonous serpents which are found in Palestine, and which is the more dangerous on account of its nocturnal habits. This snake is one of the Katukas, and is closely allied to the dreaded Tic-polonga of Ceylon, a serpent which is so deadly, and so given to infesting houses, that one of the judges was actually driven out of his official residence by it.
As to the old ideas respecting the origin of the Cockatrice, a very few words will suffice for them. This serpent was thought to be produced from an egg laid by a cock and hatched by a viper. "For they say," writes Topsel, "that when a cock groweth old, he layeth a certain egge without any shell, in stead whereof it is covered with a very thick skin, which is able to withstand the greatest force of an easie blow or fall. They say moreover that this Egge is laid only in the summer time, about the beginning of Dog days, being not so long as a Hen's Egge, but round and orbicular. Sometimes of a dirty, sometimes of a boxy, and sometimes of yellowish muddy colour, which Egge, afterwards sat upon by a Snake or a Toad, bringeth forth the Cockatrice, being half a foot in length, the hinder part like a Snake, the former part like a Cock, because of a treble combe on his forehead.
