Matthew 14:6

γενεσίοις γενομένοις : one expects the genitive absolute as in T.R., which just on that account is to be suspected. The dative of time. But cf. Mark 6:21, where we have γενομένης and γενεσίοις occurring together, and vide Weiss, Mk.-Evang., p. 221, on the literary connection between the two texts. Most commentators take γενεσίοις as referring to Herod's birthday. Some, e.g., Grotius, think of the anniversary of the accession to the throne = birthday of his reign. In classic Greek it means a feast in honour of the dead on their birthday, γενέθλια being the word for a birthday feast, vide Lobeck, Phryn., 103. Loesner, Observ. ad N. T. e. Phil. Alex., cites instances from Philo of the use of both words in the sense of a birthday feast. ἡ θυγάτηρ τ. Ἡρῳδ.: Salome by name. ἐν τῷ μέσῳ, implies a festive assembly, as fully described in Mk.
