Albert Barnes Commentary Acts 4:30

"while thy stretchest forth thy hand to heal; and that signs and wonders may be done through the name of thy holy Servant Jesus." — Acts 4:30 (ASV)

By stretching forth thine hand, etc. The apostles not only desired boldness to speak, but they asked that God would continue to work miracles, and thus furnish them and the people with evidence of the truth of what they delivered. They did not even ask that he would preserve their lives or keep them from danger. They were intent on their work, and they confidently committed their way to God, making it their primary goal to promote the knowledge of the truth, and seeking that God would glorify himself by establishing his kingdom among men.

Signs and wonders. Miracles. See Barnes on Acts 2:43.
