Augustine of Hippo
Moses designated individuals from the community of God to oversee the instruction in reading and writing, even though they were unfamiliar with any aspect of divine law. The Scriptures refer to them as grammatoeisagogous, meaning those who guide others into writing, as they somehow instill the written word within the hearts of the learners or, more accurately, translate those they educate into writing (cf. Jer. 31:33; Heb. 8:10).
