Acts 4:30 - Matthew Poole's English Annotations on the Holy Bible

By stretching forth thine hand; they desire nothing else to embolden them, but God's owning them and their work. That signs and wonders may be done: miracles were then necessary, as being the seal of their commission from God; they desire to have this patent with them, to show as often as occasion served. By the name of thy holy child Jesus; by the power and authority of Christ; for Christ alone they sought to advance and magnify, and not themselves, by all the wonders they wrought.
