A.T. Robertson Commentary 2 Corinthians 6:5

"in stripes, in imprisonments, in tumults, in labors, in watchings, in fastings;" — 2 Corinthians 6:5 (ASV)

In stripes (εν πληγαις). In blows, wounds (Luke 10:30; Luke 12:48; Acts 16:23,33). Our plague.

In tumults (εν ακαταστασιαις). See on 1 Corinthians 14:33). Instabilities, often from politics.

In watchings (εν αγρυπνιαις). In sleeplessnesses, instances of insomnia. Old word, in N.T. only here and 11:27. Paul knew all about this.
