Bridgeway Bible Dictionary [1]

When the Bible mentions the husband and wife team of Aquila and Priscilla (or Prisca), it usually mentions Priscilla first ( Acts 18:26;  Romans 16:3 AQUILA.)">1 Timothy 4:19). This is unusual, but the Bible gives no reason for such usage. Perhaps Priscilla was more active or more prominent than Aquila in the Christian work in which they were constantly and wholeheartedly engaged. (For details see Aquila .)

Fausset's Bible Dictionary [2]

Diminutive of Prisca. (See Aquila .) A sample of what married women can do for the Lord's cause, as Phoebe is of what unmarried women can do. Timothy at Ephesus would find her counsel invaluable in dealing with the female part of his flock, his position as a young man needing delicacy and discretion in relation to them ( 2 Timothy 4:19;  Romans 16:3;  1 Corinthians 16:19;  Acts 18:2;  Acts 18:26).

Watson's Biblical & Theological Dictionary [3]

a Christian woman, well known in the Acts, and in St. Paul's epistles; sometimes placed before her husband Aquila. From Ephesus this pious pair went to Rome, where they were when St. Paul wrote his epistle to the Romans, A.D. 58. He salutes them the first of all, with great commendations,  Romans 16:3 . They returned into Asia sometime afterward; and St. Paul, writing to Timothy, desires him to salute them on his behalf,  2 Timothy 4:19 , A.D. 65.

Hawker's Poor Man's Concordance And Dictionary [4]

One of Whom Paul the apostle speaks highly,  Romans 16:3-5. It is probable that this is the same person spoken of by the same apostle,  2 Timothy 4:19. It should seem tint she and her husband Aquila, had offered their house for worship. What a lovely view of saints of God!

Aquila And Priscilla

Cyclopedia of Biblical, Theological and Ecclesiastical Literature [7]

( Πρίσκιλλα , dim. from Prisca, Lat. ancient), the wife of Aquila, and probably, like Phoebe, a deaconess. She shared the travels, labors, and dangers of her husband, and is always named along with him ( Romans 16:3;  1 Corinthians 16:19;  2 Timothy 4:19), A.D. 55-64. The name is Prisca ( Πρίσκα ) in  2 Timothy 4:19, and (according to the true reading) in  Romans 16:3, and also (according to some of the best MSS.) in  1 Corinthians 16:19. Such variation in a Roman name is by no means unusual. We find that the name of the wife is placed before that of the husband in  Romans 16:3;  2 Timothy 4:19, and (according to some of the best MSS.) in  Acts 18:26. It is only in  Acts 18:2 and  1 Corinthians 16:19 that Aquila has unequivocally the first place. Hence we should be disposed to conclude that Priscilla was the more energetic character of the two; and it is particularly to be noticed that she took part, not only in her husband's exercise of hospitality, but likewise in the theological instruction of Apollos. Yet we observe that the husband and the wife are always mentioned together. In fact, we may say that Priscilla is the example of what the married woman may do, for the general service of the Church, in conjunction with home duties, as Phoebe is the type of the unmarried servant of the Church, or deaconess. Such female ministration was of essential importance in the state of society in the midst of which the early Christian communities were formed. The remarks of archdeacon Evans on the position of Timothy at Ephesus are very just. "In his dealings with the female part of his flock, which, in that time and country, required peculiar delicacy and discretion, the counsel of the experienced Priscilla would be invaluable. Where, for instance, could he obtain more prudent and faithful advice than hers in the selection of widows to be placed upon the eleemosynary list of tie Church, and of deaconesses for the ministry?" (Script. Biog. 2, 298). It seems more to our purpose to lay stress on this than on the theological learning of Priscilla. Yet Winer mentions a monograph De Priscilla, Aquilae uxore, tamquam feminarum e gente Judaica eruditarum specimine, by G. G. Zeltner (Altorf, 1709). (See Aquila).
