According to Acts 20:7, “On the first day of the week, when the disciples came together to break bread, Paul, ready to depart the next day, spoke to them and continued his message until midnight.”
Admittedly, to “break bread” in Bible times often referred to the eating of common meals. In ancient times, to “break bread” was a figure of speech known as synecdoche where a part (to break bread) was put for the whole (to eat a common meal, regardless of the kind of food and drink consumed).
