Acts of the Apostles 2:40-43

Then Peter continued preaching for a long time, strongly urging all his listeners, “Save yourselves from this crooked generation!” Those who believed what Peter said were baptized and added to the church that day—about 3,000 in all. All the believers devoted themselves to the apostles’ teaching, and to fellowship, and to sharing in meals (including the Lord’s Supper), and to prayer. A deep sense of awe came over them all, and the apostles performed many miraculous signs and wonders.
