The Greek that is often translated as «judge» in English has the option of various terms in Luang with different shades of meaning.

For Acts 4:21 and 10:42, maktorna wathudi lokarni-taitiaili lahanu («the one who holds the scales»). «This term is used when judgment of sin or wrong is in focus.»

For Acts 13:20, maktorna deulu-tatra («the one who holds the law»). «This term is used for the judges in the Old Testament for whom judging wrong was only a part of their job.»
