a flooding, flood. On the form πλημύρα in Luk_6:48 DW al. , as the older spelling, see Moulton Gr. ii. p. 101. The verb is found with a single μ in OGIS 666 .8 (A.D. 54 68), where Egypt is described as πλημύρουσα πᾶσιν ἀγαθοῖς owing to the good deeds of the praefect Tiberius Claudius Balbillus, and in P Lond 924 .10 (A.D. 187 188) (= III. p. 134) πλημυρέντος τοῦ Νείλου . For double μ see Vett. Val. p. 344 .13 f. and Artem. pp. 123 .21 (of a well) πλημμυροῦντος τοῦ ὕδατος and 124 .8 (of springs) ὕδατι καθαρῳ πλημμυροῦσαι .
