TRISAGION
According to Wikipedia, the word trisagion is from the Greek tris- (three) + hagios (holy). It is pronounced tree-sah-yon. The Trisagion ('Thrice Holy') is a standard hymn of the Divine Liturgy in most of the Eastern Orthodox Churches, Oriental Orthodox Churches and Eastern Catholic Churches.
The Trisagion prayer is considered one of the oldest prayers in Christianity. It may be that the prayer was originally an expansion of the angelic cry recorded in Revelation 4:8 (sometimes called the Sanctus).
