Moulton & Milligan — Vocabulary of the Greek NT
ἄχυρον [page 100]
A few citations suffice for this very common word, which survives in MGr. One shows that bricks without straw were as abnormal in the Ptolemaic period as in the days of the Exodus : P Petr II. 14 (2) 12 (as amended III. p. 139) shows directions ἐς τὰ ἄχυρα πρὸς τὴν πλινθολκίαν . So in Syll 587 .73 (B.C. 329 8, Attica) ἀχύρων σάκοι εἰς τὴν οἰκοδομίαν τοῦ τείχους : Ditt. cites another Attic inscr. which mentions πηλὸς ἠχυρωμένος . This use of chaff was accordingly not limited to Egypt. The practice exemplified typically in the Ptolemaic ostracon, Ostr 1168 λό (γος ) ἀχύρου , an account for fuel εἰς τὰς καμείνους , and in BGU III. 760 .9 (ii/A.D.) ἄ . τὰ καὶ χωροῦντα ἰς ὑπόκαυσιν τοῦ με [γά ]λου γυμ (νασίου ), P Fay Ostr 21 (A.D. 306) ἀχύρου καυσίμου σάκ (κον ) ᾱ reminds us that (brickmaking apart) feeding the fire was the normal use of the chaff. The stern theology of earlier days may have glossed the Baptist s words with Pro_16:4 !
