To do good (th eupoiia). Genitive case. Late compound from eupoio (eupoiew), common in Epictetus, but here only in N.T., a doing good. To communicate (koinwnia). Genitive case. See 2 Corinthians 9:13 for use for contribution, beneficence. Moffatt notes that the three great definitions of worship and religious service in the N.T. (here, Romans 12:1 ; James 1:27 ) are all inward and ethical. Forget not (mh epilanqanesqe). Prohibition with mh and the present middle imperative of epilanqanw ( James 6:10 ; James 13:2 ). Here with the genitive case. Is well pleased (euaresteitai). Present passive indicative of euarestew ( Hebrews 11:5 ). With the associative instrumental case qusiai (sacrifices).
