Jubilees 3:28
27 On that day, as he was leaving the Garden of Eden, he burned incense as a pleasing fragrance — frankincense, galbanum, stacte, and aromatic spices — in the early morning when the sun rose at the time when he covered his shame. 28 On that day the mouths of all the animals, the cattle, the birds, everything that walks and everything that moves about were made incapable of speaking because all of them used to converse with one another in one language and one tongue. 29 He dismissed from the Garden of Eden all the animate beings that were in the Garden of Eden. All animate beings were dispersed — each by its kind and each by its nature — into the places which had been created for them. 30 But of all the animals and cattle he permitted Adam alone to cover his shame.
Josephus Antiquities of the Jews 1.40
4 God therefore commanded that Adam and his wife should eat of all the rest of the plants, but to abstain from the Tree of Knowledge; and foretold to them, that if they touched it, it would prove their destruction. But while all the living creatures had one language at that time, the serpent, which then lived together with Adam and his wife, shewed an envious disposition, at his supposal of their living happily, and in obedience to the commands of God. And imagining that when they disobeyed them they would fall into calamities, he persuaded the woman, out of a malicious intention, to taste of the Tree of Knowledge: telling them, that in that tree was the Knowledge of Good and Evil: which knowledge when they should obtain they would lead a happy life; nay a life not inferior to that of a God. By which means he overcame the woman, and persuaded her, to despise the command of God. Now when she had tasted of that tree, and was pleased with its fruit, she persuaded Adam to make use of it also. Upon this they perceived that they were become naked to one another; and being ashamed thus to appear abroad, they invented somewhat to cover them; for the tree sharpened their understanding; and they covered themselves with fig-leaves; and tying these before them, out of modesty, they thought they were happier than they were before; as they had discovered what they were in want of. But when God came into the garden, Adam, who was wont before to come and converse with him, being conscious of his wicked behaviour, went out of the way. This behaviour surprized God: and he asked what was the cause of this his procedure? And why he, that before delighted in that conversation, did now fly from it, and avoid it? When he made no reply, as conscious to himself that he had transgressed the command of God; God said, “I had before determined about you both, how you might lead an happy life, without any affliction, and care, and vexation of soul; and that all things which might contribute to your enjoyment and pleasure should grow up by my providence, of their own accord, without your own labour and pains-taking: which state of labour and pains-taking would soon bring on old age, and death would not be at any remote distance. But now thou hast abused this my good will, and hast disobeyed my commands: for thy silence is not the sign of thy virtue, but of thy evil conscience.” However, Adam excused his sin; and intreated God not to be angry at him; and laid the blame of what was done upon his wife, and said that he was deceived by her, and thence became an offender. While she again accused the serpent. But God allotted him punishment, because he weakly submitted to the counsel of his wife; and said, the ground should not henceforth yield its fruits of its own accord, but that when it should be harassed by their labour, it should bring forth some of its fruits, and refuse to bring forth others. He also made Eve liable to the inconveniency of breeding, and the sharp pains of bringing forth children: and this because she persuaded Adam with the same arguments wherewith the Serpent had persuaded her; and had thereby brought him into a calamitous condition. He also deprived the Serpent of speech, out of indignation at his malicious disposition towards Adam. Besides this, he inserted poison under his tongue, and made him an enemy to men; and suggested to them that they should direct their strokes against his head; that being the place wherein lay his mischievous designs towards men; and it being easiest to take vengeance on him that way. And when he had deprived him of the use of his feet, he made him to go rolling all along, and dragging himself upon the ground. And when God had appointed these penalties for them, he removed Adam and Eve out of the garden into another Place.
Notes and References
"... Jubilees portrays animals as even more rational than in the Bible. Language is important to Jubilees and is original to creation. Thus, it seems that even animals spoke Hebrew in the beginning. Targum Neofiti (Genesis 11:1) may also hint that animals could speak with humans and each other: “and all the inhabitants of the earth were of one tongue and one speech, and in the language of the Temple they used to converse, for through it had the world been created in the beginning.” Others writing around the time of Jubilees also unquestioningly accepted the idea of original animal speech. Josephus notes that at that time, “all the creatures spoke a common tongue” (Jewish Antiquities 1:41; compare 1:50). Philo concurs, “it is said that, in olden times ... snakes could speak with a man’s voice” (On the Creation of the World, 156). The Life of Adam and Eve (37:1–3) records the story of a serpent biting Seth while he was walking with Eve. Eve curses the serpent because it was not afraid to set itself against a human as the image of God, but the serpent “answered in a human voice: ‘O Eve, is not our enmity against you?’” ..."
