The rights and privileges of a citizen in distinction from a foreigner (Luke 15:15; 19:14; Acts 21:39). Under the Mosaic law non-Israelites, with the exception of the Moabites and the Ammonites and others mentioned in Deuteronomy 23:1-3, were admitted to the general privileges of citizenship among the Jews (Exodus 12:19; Leviticus 24:22; Numbers 15:15; 35:15; Deuteronomy 10:18; 14:29; 16:10, 14).

The right of citizenship under the Roman government was granted by the emperor to individuals, and sometimes to provinces, as a favour or as a recompense for services rendered to the state, or for a sum of money (Acts 22:28). This "freedom" secured privileges equal to those enjoyed by natives of Rome. Among the most notable of these was the provision that a man could not be bound or imprisoned without a formal trial (Acts 22:25, 26), or scourged (16:37). All Roman citizens had the right of appeal to Caesar (25:11).

The use of this term in Scripture has exclusive reference to the usages of the Roman empire. The privilege of Roman citizenship was originally acquired in various ways, as by purchase, (Acts 22:28) by military services, by favor or by manumission. The right once obtained descended to a man's children. (Acts 22:28) Among the privileges attached to citizenship we may note that a man could not be bound or imprisoned without a formal trial, (Acts 22:29) still less be scourged. (Acts 16:37) Cic. in Verr. v. 63,66. Another privilege attaching to citizenship was the appeal from a provincial tribunal to the emperor at Rome. (Acts 25:11)
