Agriculture:
You shall not eat fruit of a tree during it's first three years.
Primary Verses:
Leviticus 19:23-24
"And when ye shall come into the
land, and shall have planted all manner of trees for
food, then ye shall count the fruit thereof as
uncircumcised: three years shall it be as uncircumcised
unto you: it shall not be eaten of. But in
the fourth year all
the fruit thereof shall be holy to praise YHVH withal."
