{Testifying} (diamarturomenos). As Peter did ( Ac 2:40 )
where Luke uses this same word thoroughly Lucan and Pauline. So
again in verses  23,24 . Paul here as in  Ro 1:16  includes both
Jews and Greeks, to the Jew first. {Repentance toward God} (	(886e)
eis theon metanoian) {and faith toward our Lord Jesus} (kai
pistin eis ton kurion h(886d)(936e) I(8873)oun). These two elements run
through the Epistle to the Romans which Paul had recently written
and sent from Corinth. These two elements appear in all Paul's
preaching whether "to Jews or Gentiles, to philosophers at Athens
or to peasants at Lystra, he preached repentance toward God and
faith toward the Lord Jesus" (Knowling).
