How do the concluding verses of this chapter echo the opening verses?
Isaiah 50:10–11 (ESV)
10Who among you fears the LORD and obeys the voice of his servant? Let him who walks in darkness and has no light trust in the name of the LORD and rely on his God.
As at the start of the chapter, so here at its end, the Lord challenges his hearers with two questions, concerned with whether any among Israel fears the Lord and show that by listening to his servant.
10 Who among you fears the LORD and obeys the voice of his servant? Let him who walks in darkness and has no light trust in the name of the LORD and rely on his God.
