       n : a public official authorized to decide questions bought

  Magistrate
     a public civil officer invested with authority. The Hebrew
     shophetim, or judges, were magistrates having authority in the
     land (Deut. 1:16, 17). In Judg. 18:7 the word "magistrate"
     (A.V.) is rendered in the Revised Version "possessing
     authority", i.e., having power to do them harm by invasion. In
     the time of Ezra (9:2) and Nehemiah (2:16; 4:14; 13:11) the
     Jewish magistrates were called _seganim_, properly meaning
     "nobles." In the New Testament the Greek word _archon_, rendered
     "magistrate" (Luke 12:58; Titus 3:1), means one first in power,
     and hence a prince, as in Matt. 20:25, 1 Cor. 2:6, 8. This term
     is used of the Messiah, "Prince of the kings of the earth" (Rev.
     1:5). In Acts 16:20, 22, 35, 36, 38, the Greek term _strategos_,
     rendered "magistrate," properly signifies the leader of an army,
     a general, one having military authority. The _strategoi_ were
     the duumviri, the two praetors appointed to preside over the
     administration of justice in the colonies of the Romans. They
     were attended by the sergeants (properly lictors or "rod
     bearers").
