spirit
Compare (Acts 21:4).
In (Acts 20:22) Paul's own spirit
( See Scofield) - (1 Thessalonians 5:23)
is meant; in (Acts 21:4), the Holy Spirit is meant. Paul's motive in going to Jerusalem seems to have been his great affection for the Jews (Romans 9:1-5) and his hope that gifts of the Gentile churches, sent by him to the poor saints at Jerusalem (Romans 15:25-28) would open the hearts of the law-bound Jewish believers to the "gospel of the grace of God" (Acts 20:24).
