He brought it to His people after they went into exile as punishment for straying from God.
In Jesus, He brought it to a blind man, whom some considered had a disability as punishment for sin. Yet this man sees with faith, and calls out to Jesus as the One Who can save Him, not ceasing when people try to silence Him..
Jesus called Him, and rightly declared that Bartimaeus's faith has saved him, and sends him on his way with sight restored.
Jesus's healing demonstrates how He is a great high priest Who was called by God for the purpose of coming to restore our world. We can join with the people in the Psalm who rejoice in the great things God has done for us, and then follow after Christ in that mission.
