Meaning of HAY in English
(Heb. chatsir), the rendering of the Authorized Version in (Proverbs 27:25) and Isai 15:6 Of the Hebrew term, which occurs frequently in the Old Testament, and denotes "grass" of any kind. It is quite probable that the modern Orientals do not make hay in our sense of the term; but it is certain that the ancients did mow their grass, and probably made use of the dry material. See (Psalms 37:2) We may remark that there is an express Hebrew term for "dry grass" or "hay," viz. chashash, which, in the only two places where the word occurs, (Isaiah 5:24; 33:11) is rendered "chaff" in the Authorized Version.
