But Peter began, and expounded the matter unto them in order, saying,

and he began to speak boldly in the synagogue. But when Priscilla and Aquila heard him, they took him unto them, and expounded unto him the way of God more accurately.

And when they had appointed him a day, they came to him into his lodging in great number; to whom he expounded the matter, testifying the kingdom of God, and persuading them concerning Jesus, both from the law of Moses and from the prophets, from morning till evening.
