For more on the parallels between the Didache and the Jewish Birkat ha-Mazon, see Enrico Mazza, The Celebration of the Eucharist: The Origin of the Rite and the Development of Its Interpretation (Collegeville, MN: Liturgical Press, 1999), esp. pp. 19–26 (where he discusses these parallels) and pp. 307–309 (where he provides translations of the texts).
