Stefan Krauter has produced a new lexical study that will be of interest to students of the Pastorals:

Stefan Krauter, “Ein Geist der Besonnenheit? Σωφρονισμός in 2Tim 1,7.” Zeitschrift für die neutestamentliche Wissenschaft 114.1 (2023): 123–36.

Abstract: “Almost all current translations of 2Tim 1:7 understand σωφρονισμός in this verse as a synonym of σωφροσύνη. So do authoritative recent commentaries and dictionaries. This paper demonstrates that word formation makes this unlikely and that σωφρονισμός is never used synonymously with σωφροσύνη in ancientGreek literature. It is shown that the usual meaning of “making someone σώφρων” is possible and appropriate for 2Tim 1:7. A survey of ancient translations and interpretations of the verse by ancient Christian writers shows that most of them also consider this meaning possible and obvious.”
