that you yourself are a guide to the blind, a light to those who are in darkness

Here "the blind" and "those who walk in darkness" represent people who do not understand the law. Alternate translation: "that because you teach the law, you yourself are like a guide to blind people, and you are like a light to people who are lost in the dark" (See: rc://en/ta/man/translate/figs-parallelism and rc://en/ta/man/translate/figs-metaphor)
