Moulton & Milligan — Vocabulary of the Greek NT
χοῦς, abbreviated from xéos. The original meaning ‘‘ earth,’’ ‘earth dug out,” is seen in P Tebt I. 13!4 (B.c. 114) τὸν am’ αὐτοῦ χοῦν ἀναβεβληκότας εἰς τὰ τοῦ σημαινο(μένου) Φιλοναύ(του) κλή(ρου) χώματα, ‘had heaped the earth from it (sc. a dyke) on to the mounds of the holding of the said Philonautes’’ (Edd.), P Oxy VI. 985 (accounts—2nd half i/A.D.) ἐργά(ταις) δυσὶ σκάπτοντί(ι) χοῦν (‘‘a mound”), τό. XIV. 175829 (ii/A.D.) καλῶς ποιήσεις κατενγυήσας τὸν χοῦν ὃ ἐξέσκαψεν ᾿Ατρῆς ὁ γεωργός μου ἀπὸ τῶν ἐδαφῶν pov, and P Tebt II. 34257 (late ii/a.v.) ψ[ιἹλοῦ τόπου εἰς ἐκσκαφὴν χοὸς καὶ χαινογείου καὶ ἄμμου, ““ἃ vacant space for digging earth, porous clay and sand’”’ (Edd.). The meaning ‘‘dust,’’ as in Mk 611, Rev 1815, may be seen in Syl 500 (=* 313)?8 (B.C. 320-319) τοὺς τὸν [χ]οῦν κατα[βε]βληκότας εἰς Tas ὁδ[οἹὺς ταύτας [ἀ]ναι[ρΊ]εῖν.
