Acts 20:11-15
Acts 20:11 (KJB)
When he therefore was come up again, and had broken bread, and eaten, and talked a long while, even till break of day, so he departed.
After Eutychus was resurrected, Paul had gone back up to where he was. He then had a meal and continued to speak to the people in attendance all the way until Monday morning. Then after Paul had finished speaking, he had departed from the place where he was speaking. He had probably used the situation with Eutychus as some type of source for preaching and speaking with the people. He probably taught them about how Jesus healed people and raised people from the dead while He was here on earth.
Acts 20:12 (KJB)
And they brought the young man alive, and were not a little comforted.
Then after Paul had left, they had brought Eutychus before those who were still there and there was great comfort and joy among them. The Greek word behind young man would indicate that he was a young boy in his teens but at that time in history, boys in their teens married and had families. The fact that he was alive would have given these Christians a great boost in their faith. They would have seen the power of the Lord Jesus Christ in action which would give them a boldness to continue to proclaim the Gospel. It showed that Jesus had power over death.
Acts 20:13 (KJB)
And we went before to ship, and sailed unto Assos, there intending to take in Paul: for so had he appointed, minding himself to go afoot.
Luke and the other disciples did not stay until daybreak. They got on board the ship and sailed to Assos which was about 22 miles (35 km) south of Troas. It was in Assos where they were going to pick up Paul who had taken the trip to Assos by foot instead of sailing. It is not known why Paul wanted to be alone at that time but maybe it was a time of personal communing with the Lord where the Lord had confirmed to him that persecution awaited him in Jerusalem.
Acts 20:14 (KJB)
And when he met with us at Assos, we took him in, and came to Mitylene.
So Paul met up with his company at Assos and then they sailed to the island of Lesbos which was about 30 miles (48 km) south landing in the capital city of Mitylene. Mitylene was a favorite for Romans on vacation. Its harbor faced the coast of Asia minor and was a convenient place for the ships to stop. It is stated that the walk Paul took from Troas to Assos was a very grueling area but it showed the stamina and zeal of the Apostle Paul. It was the type of trek that many future missionaries would face all over this world.
Acts 20:15 (KJB)
And we sailed thence, and came the next day over against Chios; and the next day we arrived at Samos, and tarried at Trogyllium; and the next day we came to Miletus.
After they left Lesbos, they journeyed further south to the island of Chios which was a free city-state. Their ship had anchored there overnight and then the next day they continued their journey south to the Island of Samos which was a large island and was declared a free state by Emperor Augustus. They had stayed at Trogyllium where there was a dangerous high rock formation which could damage a ship quickly. They remained till morning because they would not have been able to navigate that narrow path till there was sufficient light. The next day they were able to sail just a little southeast to Miletus which was in the Ironia province on the west coast. Even short trips within the Aegean Sea could be dangerous.
