Le 2:11 'No grain offering which you bring to the LORD shall be made with leaven, for you shall burn no leaven nor any honey in any offering to the LORD made by fire.
Leaven represents any evil influence. The grain offering will undergo a process of decomposition when leaven is present because even a minute portion of leaven is capable of communicating a decomposing action to a large mass of dough, which in this case, is a grain offering. It does it to bread and it will do it to the grain offering.
Now honey contains live yeast. And yeast is a leavening agent. And so, leaven and honey here are prohibited because of their effect on the grain offering. The Lord Jesus' life represented by the grain offering is absolutely holy; without sin or evil.
