A marginal gloss (classified as syntactic by Adler) from ms A. Apparently from the Lexicon Syntacticum in Anecdota Graeca (Cramer 1836), with some modification made by the Suda contributer.
[1] This use of the verb with a dative of advantage is found only in patristic and Byzantine literature (Theodorus Studites, Hesychius Ecclesiasticus, John Chrysostom, Theophylact Simocatta), quoting directly or indirectly a Septuagint phrase (see next note). In Latin the verb zelo when used in this sense occurs with pro plus ablative.
[2] 3 Kingdoms 19.10, repeated 19.14. (In the Vulgate: zelo zelatus sum pro Domino Deo.) This repetition of the verb is employed by some writers of the Byzantine age, particularly Theodorus Studites (Epistles 212, 307, Sermones Catechesos Magnae 62.174).
[3] Probably taken from the same Lexicon Syntacticum as the rest of the entry (see introductory note). In any event, the original source seems to be John Chrysostom: Ad populum Antiochenum 49.24 or Eclogae 73.712.
