We do have a very ancient copy of Isaiah from the Dead Sea Scrolls which is exactly the same as the modern translations.
YOU also have THE ORIGINAL Book of Abraham! Let's see how it compares to Joseph Smith's “translation”!
Joseph Smith's fabrication...from the official LDS web page.

(I/1) [”Osiris, the god’s father], prophet of Amon-Re, King of the Gods, prophet of Min who slaughters his enemies, prophet of Khonsu, the [one who exercises] authority in Thebes,
(I/2) [. . .] . . . Hor, the justified, son of the similarly titled overseer of secrets and purifier of the god, Osorwer, the justified, born by the [housewife and sistrum-player of ]
(I/3) [Amon]-Re, Taikhibit, the justified! May your ba-spirit live among them, and may you be buried on the west [of Thebes].”
(I/4) [”O Anubis(?),51 . . .] justification(?).
(I/5) [May you give to him] a good and splendid burial on the west of Thebes as on the mountains of Ma[nu](?).”
[Osiris shall be towed in]to the great lake of Khonsu,
and likewise [the Osiris Hor, the justified,] born of Taikhibit, the justified,
after his two arms have been [placed] at his heart, while
the Breathing Document, being what
is written on its interior and exterior, shall be wrapped in royal linen and placed (under) his left arm in the midst of his heart. The remainder of his
wrapping shall be made over it. As for the one for whom this book is made,
he thus breathes like the ba-spirit[s] of the gods, forever and ever.
