Note 3 at Ac 25:21: The name Augustus means "venerable (august)" (Strong's Concordance) and was a title for the Roman emperors, much like the title Caesar (see note 1 at Lu 2:1). It was first conferred on Gaius Octavius in 27 B.C., and he became commonly known as Caesar Augustus (see note 3 at Ac 11:28). After his death, the title Augustus continued to be used of the succeeding Roman emperors. The Caesar being referred to here was Nero, who is not mentioned by name in Scripture, except in the subscript of 2 Timothy (2Ti 4:22, found in some Bibles). He is referred to, however, in Ac 17:7, 25:8, 10-12, 21, 26:32, 27:24, 28:19; and Php 4:22.
