Why Tithe?

What is a tithe? It comes from the Anglo-Saxon word teotha, meaning a tenth. Generally, it has been defined as the "tenth part of the increase arising from the profits of land and stock, allotted to the clergy for their support or devoted to religious or charitable uses". However, there have been tithes long before there were "clergy" in the Christian sense. So a more biblical definition is "the tenth part of all fruits and profits justly acquired, owed to God in recognition of his supreme dominion over man, and to be paid to the ministers of the church".
