Also the nights shall yield dew, as I spake after the flood of the earth 8. when I (or Then he) gave him precept as concerning the year of the life of Noe, and said to him: These are the years which I ordained after the weeks wherein I visited the city of men, at what time I shewed them (or him) the place of birth and the colour (or and the serpent), and I (or he) said: This is the place of which I taught the first man saying: If thou transgress not that I bade thee, all things shall be subject unto thee. But he transgressed my ways and was persuaded of his wife, and she was deceived by the serpent. And then was death ordained unto the generations of men. 9. And furthermore the Lord shewed (or, And the Lord said further: I shewed) him the ways of paradise and said unto him: These are the ways which men have lost by not walking in them, because they have sinned against me.

Why Pitre cites it
Adam's transgression brings death to all his descendants — with Sirach and 4 Ezra, one of Pitre's three Jewish roots of original sin.
Notes
Taken from the OCR (djvu.txt) of James 1917, p. 116, and cleaned by hand (double spacing and line-end hyphenation removed). The parenthetical alternatives '(or Then he)', '(or him)', '(or and the serpent)', '(or he)' are James's own textual notes and are part of his printed translation. Verse 8 begins mid-sentence in James; the tail of v. 7 is included as lead-in and v. 9 (ways of paradise) as one sentence of context.
