Easton's Bible Dictionary
Eagle, a native of Pontus, by occupation a tent-maker, whom Paul met on his first visit to Corinth (Acts 18:2). Along with his wife Priscilla he had fled from Rome in consequence of a decree (A.D. 50) by Claudius commanding all Jews to leave the city. Paul sojourned with him at Corinth, and they wrought together at their common trade, making Cilician hair-cloth for tents. On Paul's departure from Corinth after eighteen months, Aquila and his wife accompanied him to Ephesus, where they remained, while he proceeded to Syria (Acts 18:18, 26). When they became Christians we are not informed, but in Ephesus they were (1 Corinthians 16:19) Paul's "helpers in Christ Jesus." We find them afterwards at Rome (Romans 16:3), interesting themselves still in the cause of Christ. They are referred to some years after this as being at Ephesus (2 Timothy 4:19). This is the last notice we have of them.
