From aniēmi (to loosen, let up), anesis literally means a slackening of tension—like releasing a drawn bowstring. In the NT it spans a range from physical liberty (Acts 24:23, where Felix grants Paul anesis in custody) to emotional relief (2 Cor 2:13, 7:5, where Paul finds no rest for his spirit or flesh) to eschatological comfort (2 Thess 1:7, promising relief to the afflicted). Paul also uses it in 2 Corinthians 8:13 to assure the Corinthians that his collection appeal is not meant to bring them hardship. Spanish captures the breadth nicely: 'libertad' for the custodial sense, 'alivio' for emotional relief, 'descanso' for rest.
