Qumran Isaiah scroll

The word that Isaiah the son of Amoz saw concerning Judah and Jerusalem.,,, Isaiah 2:1

"The greatest Qumran treasure discovered dates to the 4th century BC. Only three centuries removed from Isaiah’s time and 26 centuries

removed from modern times, the text remained virtually unchanged compared to text a thousand years younger. It was also a single scroll, contrary to liberal claims that the book of Isaiah had two or even three authors. This demonstrates the painstaking accuracy of Jewish (and Christian) scribes who faithfully copied the Scriptures—and did not change them, as scurrilously charged by liberal skeptics."
