UBS Dictionary of the Greek New Testament
noun, f. | -ῆς
1.53 · Geographical Objects and Features · Depressions and Holes
hole, opening an opening or hole in the ground, either large as in HEB 11:38 or relatively small as in JAS 3:11 Holes would differ from caves (HEB 11:38) in that holes would be vertical openings into the ground, while caves would be more or less horizontal openings into cliffs or sides of hills. In JAS 3:11 it may be quite unnecessary, and in fact confusing, to try to translate ὀπῆς, since ἐκ τῆς αὐτῆς ὀπῆς ‘from the same opening’ would seem to be redundant with ἡ πηγή ‘spring,’ since a spring would presumably only flow from a hole or opening in the ground.

Moulton & Milligan — Vocabulary of the Greek NT
ῥοπή occurs as a v./. for ῥιπή, “ἃ moment,” in 1 Cor 1552 D*EFG 67**. For the original meaning, ‘‘a turn of the scale,” as in Sap 1812, cf. P Par 63% (B.c. 165) (as read P Petr III. p. 24) συμβαλεῖται ῥοπὴν eis τὸ προκίμενον, “it would turn the scale in favour of the matter in hand” (Mahaffy), and P Tebt I. 2779 (cited s.v. ἐνθυμέομαι). See also Aristeas 90 ῥοπῇ καὶ νεύματι, ‘momento temporis et ad nutum,” Vett. Val. p. 3011 at στιγμαὶ ἢ poral τῶν ὡρῶν, and Herodas VII. 33 with Headlam’s note. “Ῥοῦφος. For the probable identification of the Ῥοῦφος of Rom 1678 with the Ῥοῦφος of Mk 15%, see SH p. 426f. The name is very common: see e.g. P Hamb I. 29° (A.D. 89), and the reff. in Preisigke Mamenbuch s.v. OZ? ῥύμη. ͵ r For this word in its late Greek sense ‘‘ street,” ‘lane, which it has in its four occurrences in the NT (Mt 65, e , pvopac Lk 1421, Ac 944, 1219), cf. P Par 5126 (B.c. 159) (= UPZi. Ῥ. 360, Selections, p. 20) ἔρχομαι eis τὴν ῥύβ(-- μ)ην μετ᾽ αὐτῶν, BGU IV. το371 (A.D. 47) εἰς τὴν ἐκ λιβὸς ῥύμην βασιλικήϊν, P Oxy I. οο9 (A.D. 55) ἀνὰ μέσον οὔσης τυφλῆς ῥύμης (‘blind alley”), and P Ryl 11. 1564 (i/A.p.) δημοσία ῥύμη. In an Alexandrian papyrus of the time of Augustus we hear of a street named EvSaipwv—ev τῆι Εἰὐδαίμονος λεγομένηι ῥύμηι (see Archiv v. p. 37 n.1). For the diminutive ῥύμιον (not in 1,55) = ‘‘a little lane” or ‘‘alley,”’ cf. the direction in P Meyer 20 verso® (1st half iii/A.D.) ἀντικρὺ τοῦ [...] πωλίου ἥκεις (εἰς) TO ῥύμιον, ‘‘over against the shop you come to the little lane.” See further Rutherford VP p. 487 f., and Kennedy Sources p- 15f., where the different stages in the history of ῥύμη are stated.
