4. Easton's 1897 Bible Dictionary

Leaven
   (1.) Heb. seor (Ex. 12:15, 19; 13:7; Lev. 2:11), the remnant of
   dough from the preceding baking which had fermented and become
   acid.
   
     (2.) Heb. hamets, properly "ferment." In Num. 6:3, "vinegar of
   wine" is more correctly "fermented wine." In Ex. 13:7, the
   proper rendering would be, "Unfermented things [Heb. matstsoth]
   shall be consumed during the seven days; and there shall not be
   seen with thee fermented things [hamets], and there shall not be
   seen with thee leavened mass [seor] in all thy borders." The
   chemical definition of ferment or yeast is "a substance in a
   state of putrefaction, the atoms of which are in a continual
   motion."
   
     The use of leaven was strictly forbidden in all offerings made
   to the Lord by fire (Lev. 2:11; 7:12; 8:2; Num. 6:15). Its
   secretly penetrating and diffusive power is referred to in 1
   Cor. 5:6. In this respect it is used to illustrate the growth of
   the kingdom of heaven both in the individual heart and in the
   world (Matt. 13:33). It is a figure also of corruptness and of
   perverseness of heart and life (Matt. 16:6, 11; Mark 8:15; 1
   Cor. 5:7, 8).
