Tithe (from Old English teogoþa "tenth")

A tithe (from Old English teogoþa "tenth") is a one-tenth part of something, paid as a (usually) voluntary contribution or as a tax or levy, usually to support a Jewish or Christian religious organization. Today, tithes (or tithing) are normally voluntary and paid in cash, cheques, or stocks, whereas historically tithes could be paid in kind, such as agricultural products. Several European countries operate a formal process linked to the tax system allowing some churches to assess tithes.
