Properly so called, was not in use among the Hebrews; straw was used instead. They cut the grass green as it was needed. The word rendered “hay” in Prov. 27:25 means the first shoots of the grass. In Isa. 15:6 the Revised Version has correctly “grass,” where the Authorized Version has “hay.”
Hay
Hay turns up three times, and each time it is a plain plant. In Proverbs 27:25 “the hay appeareth, and the tender grass sheweth itself,” a sign of a changing season and of work for the farmer. In Isaiah 15:6 the picture turns dark: Moab’s waters are desolate and “the hay is withered away.” Paul gives it a third use. A builder may put up a church’s work with “gold, silver, precious stones, wood, hay, stubble,” and the first three are what lasts. Read 1 Corinthians 3:10-15 to see how the rest of his picture goes.
