These are the verses:
7 On the first day of the week we came together to break bread. Paul spoke to the people and, because he intended to leave the next day, kept on talking until midnight. 8 There were many lamps in the upstairs room where we were meeting. 9 Seated in a window was a young man named Eutychus, who was sinking into a deep sleep as Paul talked on and on. When he was sound asleep, he fell to the ground from the third story and was picked up dead. 10 Paul went down, threw himself on the young man and put his arms around him. “Don’t be alarmed,” he said. “He’s alive!” 11 Then he went upstairs again and broke bread and ate. After talking until daylight, he left. 12 The people took the young man home alive and were greatly comforted. NIV
I would first think that "break bread" means partaking of the Eucharist or the Communion, because it was the first day of the week. But the verses seem to be saying it only in passing and not really saying that Paul was observing a religious rite. Also, he does it twice in the same day, which is also confusing if it is the Eucharist.
