Note 1 at Acts 20:7: This is probably referring to communion, the taking of the Lord's supper (Mt. 26:26-29; Mk. 14:22-25; Lk. 22:19-20), since in 1 Cor. 10:16, this same terminology is clearly applied to the Lord's supper.

Note 2 at Acts 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 bringing his total ministry to 12 hours or more.

This is not the only time that Paul was "long-winded." In Acts 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 people left everything and came out to him for three days of ministry (Mt. 15:32; Mk. 8:1- 3).

This says quite a bit about the power that Jesus and Paul ministered in. 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 also is no virtue in keeping it short when the power of God is moving.
