In Acts 13, the Holy Spirit said to set apart Saul and whom for His work?

Answer: Barnabas

As the church at Antioch worshiped and fasted, the Holy Spirit said, "Set apart for Me Barnabas and Saul for the work."

“Now in the church at Antioch there were prophets and teachers: Barnabas, Simeon called Niger, Lucius of Cyrene, Manaen (who had been brought up with Herod the tetrarch), and Saul. While they were worshiping the Lord and fasting, the Holy Spirit said, “Set apart for Me Barnabas and Saul for the work to which I have called them.””— Acts 13:1-2 (BSB)
