Ruth 3:2

Verse Ruth 3:2. He winnoweth barley tonight] It is very likely that the winnowing of grain was effected by taking up, in a broad thin vessel or sieve, a portion of the corn, and letting it down slowly in the wind; thus the grain would, by its own weight, fall in one place, while the chaff, c., would be carried to a distance by the wind. It is said here that this was done at night probably what was threshed out in the day was winnowed in the evening, when the sea breeze set in, which was common in Palestine; and as this took place in the evening only, that was the time in which they would naturally winnow their corn.
