¹ sn Tiberius Caesar was the Roman emperor Tiberius Claudius Caesar Augustus, who ruled from a.d. 14-37.

⁴ sn Caesar Augustus refers to Octavian, who was Caesar from 27 b.c. to a.d. 14. He was known for his administrative prowess.

¹ tn A designation of the Roman emperor (in this case, Nero). BDAG 917 s.v. σεβαστός states, “ὁ Σεβαστός His Majesty the Emperor Ac 25:21, 25 (of Nero).” It was a translation into Greek of the Latin “Augustus.”

⁴ tn According to BDAG 917 s.v. σεβαστός, “In σπεῖρα Σεβαστή 27:1 (cp. OGI 421) Σεβαστή is likew. an exact transl. of Lat. Augusta, an honorary title freq. given to auxiliary troops (Ptolem. renders it Σεβαστή in connection w. three legions that bore it: 2, 3, 30; 2, 9, 18; 4, 3, 30) imperial cohort.” According to W. Foerster (TDNT 7:175), “In Ac. 27:1 the σπεῖρα Σεβαστή is an expression also found elsewhere for ‘auxiliary troops.’” In no case would this refer to a special imperial bodyguard, and to translate “imperial regiment” or “imperial cohort” might give this impression. There is some archaeological evidence for a Cohors Augusta I stationed in Syria during the time of Augustus, but whether this is the same unit is very debatable.

¹ sn The main city of Samaria most likely refers to the principal city of Samaria, rebuilt by Herod the Great as Sebaste in honor of Augustus (J. Boehmer, “Studien zur Geographie Palästinas bes. im Neuen Testament,” ZNW 9 [1908]: 216-18; D. Gill and C. Gempf, eds., The Book of Acts in its Graeco-Roman Setting, 272). This is the best option if the article before “city” is taken as original. If the reading without the article is taken as autographic, then another city may be in view: Gitta, the hometown of Simon Magus according to Justin Martyr (cf. C. K. Barrett, Acts [ICC], 1:402-3; F. F. Bruce, Acts [NICNT], 165).
