Acts 4:30

By stretching forth thine hand to heal
That is, by exerting his power in healing sicknesses, diseases, and lameness, as in the above instance, by the hands of the apostles; which, as it would be contrary to the schemes of the Jewish sanhedrim, and would confirm the doctrines of the Gospel; so it would animate the preachers of the word to preach it with more readiness, cheerfulness, and firmness of mind; and that signs and wonders may be done by the name of thy holy child
Jesus;
as had been done already, and by whose name particularly the lame man at the temple had received a cure, and in whose name the sanhedrim had forbid the apostles to preach, or to make use of it, in doing any other miracle.
