Note 1 at Ac 20:7: This is probably referring to communion, the taking of the Lord's Supper (Mt 26:26-29, Mr 14:22-25, and Lu 22:19-20), since this same terminology is clearly applied to the Lord's Supper in 1Co 10:16.

Note 2 at Ac 20:7: This message of Paul's could have been six hours long or more. After the raising of Eutychus from the dead, Paul started preaching again till the break of day (Ac 20:11), bringing his total ministry to twelve hours or more.

This is not the only time that Paul was long-winded. In Ac 28:23, Luke said that Paul taught the people from the Word of God from morning to evening. Jesus also had some marathon sessions, like the one where the people left everything and came out to where He was for three days of ministry (Mt 15:32 and Mr 8:1-3).

This says quite a bit about the power in which Jesus and Paul ministered. People today would sit for hours, too, if the power of God was in manifestation to meet all their needs. There is no virtue in long messages if no power is present. However, there is also no virtue in keeping it short when the power of God is moving.
