The servant uses these questions to identify those to whom he is speaking. Alternate translation: "If someone among you fears Yahweh and obeys the voice of his servant, but he walks in deep darkness without light, then he should ... his God." (See: [[rc://en/ta/man/jit/figs-rquestion]])
The servant speaks of people who are suffering and feel helpless as if they were walking in a very dark place. Alternate translation: "is suffering and feels helpless" (See: [[rc://en/ta/man/jit/figs-metaphor]])
These two phrases mean basically the same thing. Here the word "name" represents Yahweh himself. Trusting in God is spoken of as if it were leaning on him. Alternate translation: "trust in Yahweh, his God" (See: [[rc://en/ta/man/jit/figs-parallelism]] and [[rc://en/ta/man/jit/figs-metonymy]] and [[rc://en/ta/man/jit/figs-metaphor]])
