'Release' in the Bible

"The Spirit of the Lord is upon me; he has anointed me to tell the good news to the poor. He has sent me to announce release to the prisoners and recovery of sight to the blind, to set oppressed people free,

Now he was obligated to release someone for them at the festival.

But they all shouted out together, "Away with this man! Release Barabbas for us!"

So he released the man who had been put in prison for revolt and murder the man whose release they continued to demand but he let them have their way with Jesus.
