The following article is dedicated to the interpretation of two unique textual variants — TWRTYW and YNHYLW, which can be found in the Great Isaiah Scroll (1QIsaa) in Isa 42:4b. This scroll is the oldest Hebrew manuscript of the Book of Isaiah and dates back to the second part of 2nd century BC. Up until today the reason for the appearance of these variants as well as the meaning of the passage, in which they are found, were unclear.
