Acts 4:31

Overview - Acts 4
The rulers of the Jews, offended with Peter's sermon,
imprison him and John.
After, upon examination Peter boldly avouching the lame man to be healed by the name of Jesus, and that by the same Jesus only we must be eternally saved,
13 they command him and John to preach no more in that name, adding also threatening;
23 whereupon the church flees to prayer.
31 And God, by moving the place where they were assembled, testifies that he heard their prayer; confirming the church with the gift of the Holy Ghost, and with mutual love and charity.
