Easton's 1897 Bible Dictionary:

Hay
   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."
