Who is one inwardly (o en twi kruptwi). Repeat Ioudaio (Jew) here also, "the in the inward part Jew" (circumcision of the heart peritomh kardia and not a mere surgical operation as in Colossians 2:11 , in the spirit en pneumati, with which compare 2 Corinthians 3:32 Corinthians 3:6 ). This inward or inside Jew who lives up to his covenant relation with God is the high standard that Paul puts before the merely professional Jew described above. Whose praise (ou o epaino). The antecedent of the relative ou is Ioudaio (Jew). Probably (Gifford) a reference to the etymology of Judah (praise) as seen in Ga 49:8.
