'Set at Liberty' in the Bible

The Spirit of the Lord is upon me, Because he anointed me to preach good tidings to the poor: He hath sent me to proclaim release to the captives, And recovering of sight to the blind, To set at liberty them that are bruised,

And Agrippa said unto Festus, This man might have been set at liberty, if he had not appealed unto Caesar.

Know ye that our brother Timothy hath been set at liberty; with whom, if he come shortly, I will see you.
