Commentary on the Didache and on 1–2 Clement

Knopf's commentary on the Didache and 1–2 Clement was originally entitled Die Apostolischen Vater, Band 1: Die Lehre der zwolf Apostel: Die zwei Clemensbriefe and was published in the Handbuch zum Neuen Testament: Erganzung-band in 1920. The volume contains introductory information for the Didache and 1–2 Clement, a translation of these texts, and accompanying critical commentary which proceeds verse by verse.
