A tenth part, or 10 percent, given or paid as a tribute, especially for religious purposes. It is also called a “tithe,” and giving it is called “tithing.” (Mal 3:10; De 26:12; Mt 23:23) Under the Mosaic Law, a tenth of the produce of the land and a tenth of the increase of the herds and flocks were given to the Levites yearly to support them. The Levites gave a tenth of this tenth to the Aaronic priesthood to support them. There were some additional tithes as well. Tithing is not required of Christians.
