Acts 13:43

τῶν σεβομένων προσηλύτων, of devout proselytes. This name may have been used to distinguish those proselytes who conformed entirely to Judaism from the proselytes of the gate.

ἔπειθον αὐτοὺς προσμένειν τῇ χάριτι τοῦ θεοῦ, persuaded them to continue in the grace of God, as Barnabas in like circumstances had urged on the converts at Antioch in Syria (Acts 11:23). Here, though we have no mention of actual converts, the Apostles must have had regard to the ‘purpose of their hearts’ when they spake to these inquirers as though they were already ‘in the grace of God.’
