A tithe, means the tenth-part of something, usually income, paid to a religious organization. [1] A tithe can be seen as a tax, a fee for a service or a voluntary contribution.[2] [2] Tithing came from the Book of Numbers.[3] In ancient Israel, the tribes of Levites were the priests.[3] The other tribes gave tithes to the tribes of Levies because they had been given no land in Canaan.[3] Tithes may be money or crops or other valuable thing.
