Robertson's Word Pictures (NT)
I can do all things (panta isxuw). Old verb to have strength (isxuv).
In him that strengtheneth me (en tw endunamounti me). Late and rare verb (in LXX) from adjective endunamov (en, dunamiv). Causative verb to empower, to pour power into one. See same phrase in I Timothy 1:12 tw endunamwsanti me (aorist tense here). Paul has such strength so long as Jesus keeps on putting power (dunamiv) into him.
