14.17 · Physical Events and States · Events Involving Liquids and Dry Masses
to flow, a flow the movement of a liquid in some direction In a number of languages a term referring to the flow of liquid may also be applied to the movement of any object, so that a literal rendering might be ‘the liquid moved.’ However, terms for ‘flow’ or ‘pour’ often differ substantially on the basis of the direction of the flow. For example, if the flow is relatively horizontal, and therefore slow, it may have one term, while if it is quite fast, another expression may be used, and if the flow is almost perpendicular (as in the case of pouring), a still different term is employed.
1 It is possible to regard ῥέω ‘to flow’ and ῥύσις[a] ‘a flow or a flowing’ as being semantically distinct on the basis that one refers only to the event of flowing, while the second particularizes the event by assuming a specific beginning and end point and thus making it possible to speak of a number of such events. In English this type of semantic derivation is almost automatic between verbs and nouns, and it is widespread in Greek, though with obvious morphological differences. In a number of other languages, however, there is no corresponding noun form, and in order to speak of a series of events, one must simply say it flowed several times.

ῥέω. For péw, ““ flow,” which occurs in the NT only in Jn 738 (for fut. act. οἵ. Pro/eg. p. 154), see the traveller’s account of his visit to the source of the Nile, P Lond 8548 (i/ii a.p. ) (=III. p. 206, Deissmann LAE p. 162) ὅθεν t[vy]xaver Νεῖλος ῥέων, ‘‘whence the Nile flows out”: cf. P Lond 1216 (jii/A.D.) (=I. p. 98) παρὰ ῥέον βαλανείου and Pretsighke 40179 (A.D. 10-11) ποταμ[ὸν] . . ῥέοντα δι᾿ ὅλης τῆς πόλεως. For the subst. ῥεῦμα, cf. P Petr II. 37 2a verso! (iii/B.c.) ἐνκλείναντος τ[οὔ] ῥεύματος εἰς τὸ πρὸς βορρᾶν μέρος, and P Lond 467°8 (iv/a.p.) (= I. p. 73) ἐν τῷ ῥεύματι τοῦ ποταμοῦ εἰς τὴν OdAacoay. “Ρήγιον, ““Rhegium” (mod. ‘‘ Reggio”), a town in Italy opposite Sicily. For the derivation of the name from ῥήγνυμι see the citations in Wetstein ad Ac 281%, t~ ῥῆγμα. For ῥῆγμα in the sense of ‘‘ breach”’ in the Nile embankments see P Lond 131 γεοίοϑθ, 60 (a.p. 78-9) (=I. p. 171 f.), and cf. PSI V. 4561 (a.p. 276-82) ἐπὶ τοῦ mipyov.. ῥήγματα : cf. Lk 639, and for the medical use of the word = “‘rupture,” see Hobart p. 56. The subst. ῥηγμός may be illustrated from 74. IV. 422) (iii/B.c.) ἡ δὲ γῆ ῥηγμῶν πλήρε( -Ξη)ς ἐστὶν διὰ τὸ μήποτε αὐτὴν ἠρόσθαι. ῥήγνυμι, ῥήσσω, “rend,” ‘break asunder”: P Leid V-31 (iii/iv A.D.) (= ΤΙ. p. 27) at πέτραι ἀκούσασαι ῥήγυνται (1. ῥήγνυνται). Ῥήσσω is claimed as Ionic by Winer-Schmiedel, p. 19. For ῥάσσω see Mk g!® D. In the LXX ῥάσσω is not an alternative of ῥήσσω, but a form of ἀράσσω : see Thackeray Gr. i. p. 76. t~ ῥῆμα. For the ordinary meaning ‘‘ word” in the NT, cf. P Giss I, go. 7 (A.D. 215) ἐκ τῶν ῥηϊμά͵των το[Ὁ] προτέρου διατάγματος, P Ambh II. 1425 (iv/A.D.) ἀπρεπῆ ῥήματα, P Flor III. 3094 (iv/A.p.) αἰσχρ[ο]ῖς ῥήμασι, and Sy// 809 (=*1175)!8 (iv/iii B.C.) ῥῆμα μοχθηρὸν ἢ πονηρὸν φθένγεσθαι (contrasted with 39 κακόν τι ποῆσαι). On the Hebraistic use = ves in the LXX and in the more Hebraic parts of Luke’s writings (Lk 187, 2%, a@/.), see Thackeray Gr. i. p. 41. A somewhat similar use of λόγος has classical authority, e.g. Plato Phz/. 33 C.
