Isaiah 59:5

5 They give birth to snake's eggs, and make spider's threads: whoever takes their eggs for food comes to his death, and the egg which is crushed becomes a poison-snake.

Isaiah 59:5 Meaning and Commentary

Isaiah 59:5

They hatch cockatrice eggs, and weave the spider's web
Invent false doctrines according to their own fancies, which may seem fair and plausible, but are poisonous and pernicious; as the "eggs [of the] cockatrice", which may look like, and may be taken for, the eggs of creatures fit to eat; and spin out of their brains a fine scheme of things, but which are as thin, and as useless, and unprofitable, as "the spider's web"; and serve only to ensnare and entangle the minds of men, and will not stand before the word of God which sweeps them away at once; particularly of this kind is the doctrine of justification by the works of men, which are like the spider's web, spun out of its own bowels; so these are from themselves, as the doctrine of them is a device of man, and is not of God: he that eateth of their eggs dieth:
as a man that eats of cockatrice eggs dies immediately, being rank poison; so he that approves of false doctrines, receives them, and feeds upon them, dies spiritually and eternally; these are damnable doctrines, which bring upon men swift destruction; they are poisonous, and eat as do a canker, and destroy the souls of men: and that which is crushed breaketh out into a viper;
or "cockatrice"; so Kimchi and Ben Melech take it to be the same creature as before, which goes by different names; and the words seem to require this sense; however, it cannot be the creature we call the viper, since that is not oviparous, but viviparous, lays not eggs, but brings forth its young; though both Aristotle ^F23 and Pliny ^F24, at the same time they say it is viviparous, yet observe that it breeds eggs within itself, which are of one colour, and soft like fishes. The Targum renders it "flying serpents": the sense is, that if a man is cautious, and does not eat of the cockatrice eggs, but sets his foot on them, and crushes them, out comes the venomous creature, and he is in danger of being hurt by it; so a man that does not embrace false doctrines, and escapes eternal death by them, but tramples upon them, opposes them, and endeavours to crush and destroy them, yet he is exposed to and brings upon himself calumnies, reproach, and persecution.

Isaiah 59:5 In-Context

3 For your hands are unclean with blood, and your fingers with sin; your lips have said false things, and your tongue gives out deceit.

4 No one puts forward an upright cause, or gives a true decision: their hope is in deceit, and their words are false; they are with child with sin, and give birth to evil.

5 They give birth to snake's eggs, and make spider's threads: whoever takes their eggs for food comes to his death, and the egg which is crushed becomes a poison-snake.

6 Their twisted threads will not make clothing, and their works will give them nothing for covering themselves: their works are works of sin, and violent acts are in their hands.

7 Their feet go quickly to evil, and they take delight in the death of the upright; their thoughts are thoughts of sin; wasting and destruction are in their ways.
