{Have we no right?} (M(8820)ouk echomen exousian;). Same idiom.
{To lead about a wife that is a believer?} (adelph(886e) gunaika
periagein;). Old verb periag(935c), intransitive in  Ac 13:11 . Two
substantives in apposition, a sister a wife, a common Greek
idiom. This is a plea for the support of the preacher's wife and
children. Plainly Paul has no wife at this time. {And Cephas}
(kai K(8870)h(8373)). Why is he singled out by name? Perhaps because of
his prominence and because of the use of his name in the
divisions in Corinth ( 1:12 ). It was well known that Peter was
married ( Mt 8:14 ). Paul mentions James by name in  Ga 1:19  as
one of the Lord's brothers. All the other apostles were either
married or had the right to be.
