a neuter plural (akin to genesis, "lineage," from ginomai), primarily denoted "the festivities of a birthday, a birthday feast," though among the Greeks it was also used of a festival in commemoration of a deceased friend. It is found in Matthew 14:6; Mark 6:21 . Some have regarded it as the day of the king's accession, but this meaning is not confirmed in Greek writings.
