Fuller’S Soap
Easton’s Bible Dictionary (1897)
(Hebrews borith mekabbeshim, i.e., “alkali of those treading cloth”). Mention is made (Proverbs 25:20; Jeremiah 2:22) of nitre and also (Malachi 3:2) of soap (Hebrews borith) used by the fuller in his operations. Nitre is found in Syria, and vegetable alkali was obtained from the ashes of certain plants. (See SOAP.)
