The scroll contains scribal errors, corrections, and more than 2600 textual variants when compared with the Masoretic codex.[1] This level of variation in 1QIsaa is much greater than other Isaiah scrolls found at Qumran, with most, such as 1QIsab, being closer to the Masoretic Text.[2] Some variants are significant and include differences in one or more verses or in several words. Most variants are more minor and include differences of a single word, alternative spellings, plural versus single usage, and changes in the order of words.[11]
