STRONGS NT 257: ἅλων

ἅλων, (ωνος, ἡ (in the Sept. also ὁ, cf. Ruth 3:2; Job 39:12), equivalent to ἡ ἅλως, genitive ἅλω, a ground-plot or threshing-floor, i. e., a place in the field itself, made hard after the harvest by a roller, where the grain was threshed out: Matthew 3:12; Luke 3:17. In both these passages, by metonymy of the container for the thing contained, ἅλων is the heap of grain, the flooring, already indeed threshed out, but still mixed with chaff and straw, like Hebrew גֹּרֶן, Ruth 3:2; Job 39:12 (the Sept. in each place ἅλωνα); (others adhere to the primary meaning. Used by Aristotle, de vent. 3, Works, 2:973{a} 14).
