Now on the first day of the Feast of the Unleavened Bread, the disciples came to Jesus, saying to Him, "Where do You desire that we shall prepare for You to eat the Passover?"
Now on the first day of the week, the disciples being assembled to break bread, Paul was discussing with them, being about to leave on the next day, and extended his message until midnight.
The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
