Acts 20:7
And upon the first day of the week, when the disciples came together to break bread, Paul preached unto them, ready to depart on the morrow; and continued his speech until midnight. And upon the first day of the week, when the disciples came together to break bread, Paul preached unto them, ready to depart on the morrow; and continued his speech until midnight.
The verse falls in Paul's journey intended to bring him to Jerusalem for Pentecost, after he changed his route because of a plot against his life. The gathering it describes took place on the last evening of his seven-day stay at Troas. A larger company than usual came together because Paul, their beloved teacher, was about to depart. They assembled in an upper room on the third story. That upper room was the coolest and pleasantest place for such a gathering on a warm spring evening, and many lights were burning because the nights were dark.
Coming together to break bread was partaking of the communion, which the believers shared after Eutychus was restored to life. The meeting was connected with that notable miracle of Eutychus being restored to life; Paul preached until midnight and, after the restoration, continued his discourse until dawn of day, until daybreak. He spoke at such length because his mind was impressed with the perils awaiting him and the uncertainty of meeting them again, because he had matter of great interest and importance to present, and in earnestness of love and solicitude for them. The meeting was held on the evening before the first day of the week and continued until daylight, while Sunday itself was spent by Paul and his companions in physical labor; it is the only religious meeting specifically mentioned as taking place on the first day of the week. The gathering on the first day to break bread does not establish Sunday as a sacred day or Sabbath and does not prove Christians must keep that day, since the disciples also broke bread from house to house on every day of the week, so such meetings were not exclusive to Sunday.
