'Accurately' in the Bible

it seemed good to me also, having traced the course of all things accurately from the first, to write unto thee in order, most excellent Theophilus;

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.
