In 1947, archaeologists discovered the Dead Sea Scrolls, known as the greatest archaeological discovery of the 20th century. The entire scroll of the book of Isaiah was found, including the famous chapter 53. Critics of the Bible have asserted that the Book of Psalms and chapters like Isaiah 53 contain information inserted many years later by the church. Yet, the discovery of the Dead Sea scrolls refutes that claim, as those scrolls included Isaiah 53 in its entirety, dated to be from 300 BC.
