(2) Tertullus, the Jewish accusers' advocate against Paul ( Acts 24:1). Paul as a Roman citizen was tried with Roman judicial forms ( Acts 25:9-10), the Roman lawyer pleading in Latin, as Norman French was formerly the language of law proceedings in England in Norman times.
Morrish Bible Dictionary 
1. lachash. This is joined with 'eloquent' in Isaiah 3:3 , A.V., but signifies 'a whisper,' 'incantation,' and may be translated 'one versed in enchantments.' The R.V. has 'skilful enchanter.' See Divination

Hastings' Dictionary of the Bible 
Orator The term applied in Acts 24:1 to Tertullus, who was the advocate for the high priest and elders against St. Paul. Men of this class were to be found in most of the provincial towns of the Roman Empire, ready to plead or defend any cause, and generally possessed of a certain amount of glib eloquence, with a due admixture of flattery.
Smith's Bible Dictionary 
Orator. The Authorized Version rendering in, Isaiah 3:3, for what is literally, "Skillful In Whisper Or Incantation". The title is applied to Tertullus, who appeared as the advocate of the Jewish accusers of St. Paul before Felix, Acts 24:1.

2. It stands for Ῥήτωρ , the title applied to Tertullus (q.v.), who appeared as the advocate or Patronus of the Jewish accusers of the apostle Paul before Felix ( Acts 24:1). The Latin language was used, and Roman forms observed in provincial judicial proceedings, as, to cite an obviously parallel case, Norman-French was for so many ages the language of English law proceedings. The trial of Paul at Caesarea was distinctly one of a Roman citizen; and thus the advocate spoke as a Roman lawyer, and probably in the Latin language (see Acts 25:9-10; comp. Val. Max. 2:2, 2; Cicero, Pro Coelio, c. 30; Brutus, c. 37, 38,41, where the qualifications of an advocate are described; see Conybeare and Howson, Life and Epistles of St. Paul, 1:3; 2:348). (See Advocate).
