What is "debtera"

A debtera (or dabtara; Ge'ez\ Tigrinya\ Amharic: ደብተራ (Däbtära); plural, Ge'ez\Tigrinya: debterat, Amharic: debtrawoch ) is an itinerant religious figure among the Beta Israel and in the Ethiopian and Eritrean Orthodox Tewahedo Churches, who sings hymns and dances for churchgoers, and who performs exorcisms and white magic to aid the congregation. A debtera will claim an ecclesiastical identity and behave as in minor orders. They may in fact be officially ordained as deacons, or may act outside the Church hierarchy. They are usually feared by the local population, who often mistake them for madmen.
