Acts 13:1-4 The Holy Spirit Sends Barnabas and Saul
“Now in the church in Antioch there were prophets and teachers, Barnabas, Simeon who was called Niger,  Lucius of Cyrene, Manaen a member of the court of Herod the tetrarch, and Saul. While they were worshipping the Lord  and fasting, the Holy Spirit said, “Set apart for me Barnabas and Saul for the work to which I have called them.” After fasting and praying they laid hands on them and sent them off.  So, being sent by the Holy Spirit, they went down to Seleucia, and from there they sailed to Cyprus.”
 Niger: Νίγερ. This is the only use of this word in the New Testament.
 worshipping the Lord: Λειτουργούντων τῷ Κυρίῳ
 “sent them off, released them” ἀπέλυσαν
 “Being sent out by the Holy Spirit,” ἐκπεμφθέντες ὑπὸ τοῦ Ἁγίου Πνεύματος. This is the only use of ἐκπεμφθέντες in the New Testament.
