Romans 15:13

The God of hope (o qeo th elpido). Taking up the idea in verse Isaiah 12 as in verse Isaiah 5 from Isaiah 4 . Fill you (plhrwsai uma). Optative (first aorist active of plhrow) of wish for the future. Cf. dwih in verse Isaiah 5 . In believing (en twi pisteuein). "In the believing" (en with locative of the articular infinitive, the idiom so common in Luke's Gospel). That ye may abound (ei to perisseuein uma). Purpose clause with ei to, as in verse Isaiah 8 , with perisseuein (present active infinitive of perisseuw, with accusative of general reference, uma). This verse gathers up the points in the preceding quotations.
