Acts 24:12

In Jerusalem there was only one temple, nor could there, by an express command of the Almighty, be any more throughout the whole kingdom. (Perhaps the Almighty may have wished by this singular circumstance to have impressed more forcibly on their minds the absolute necessity of unity in religion. (Haydock)) But there were many synagogues, which were a kind of schools, in which the law was publicly taught, and the people assembled to read the Scriptures, and to pray. (Calmet)
