1 Thessalonians 2:9
9 Our Christian friends, remember how we worked so hard when we were with you. We worked during the day and even during the night. We did not want to cause any problems for you. So we taught you God's good news and we did not ask you to give us anything in return.
2:9While Paul, Silas and Timothy were at Thessalonica, they worked to get some money. Paul knew how to make tents. See Acts 18:3.
