Matthew Poole and continuators on Acts 5:13

13 And of the rest durst no man joyn himself to them: but the people magnified them.

Such who were not of the common sort of people, and here seem to be distinguished from them; or of the rest, (more largely) who had not joyned themselves to the Church, being amazed at this judgment on these two Hypocrites, durst not make a formal shew of Religion, unless they had a thorow perswasion in their mind concerning the truth of it, and a firm resolution in their conversation to live answerably unto it.
