Then someone came and said, “Look! The men you put in jail are standing in the temple courts teaching the people.” At that, the captain went with his officers and brought the apostles. They did not use force, because they feared the people would stone them. ~ Book of Acts, Ch. 5
The ruling authority of the Jews in ancient times feared retaliation should they use force on those preaching Christ. The people's response wasn't one of human effort, might or power, rather the Spirit of the Lord moving people to obey Him over human beings.
Fascinating ancient story given the time we live. Simply fascinating.
