Robertson's Word Pictures (NT)
For the present (prov to paron). A classical phrase (Thucydides), prov with the accusative neuter singular articular participle of pareimi, to be beside.
Not joyous, but grievous (ou xaras, alla luphv). Predicate ablative (springing from) or predicate genitive (marked by). Either makes sense, but note predicate ablative in II Corinthians 4:7 (kai tou qeou kai mh ec hmwn).
Peaceable fruit (karpon eirhnikon). Old adjective from eirhnh (peace), in N.T. only here and James 3:17. Peaceable after the chastening is over.
Exercised thereby (di authv gegumnasmenoiv). Perfect passive participle (dative case) of gumnazw, state of completion, picturing the discipline as a gymnasium like Hebrews 5:14; 4:17.
