"TITHING: we are Christians, Not Jews: A Catholic perspective" By Bahago D.M

Jew, Hebrew or Yehudi, any person whose religion is Judaism. In the broader sense of the term, a Jew is any person belonging to the worldwide group that constitutes, through descent or conversion, a continuation of the ancient Jewish people, who were themselves descendants of the Hebrews of the Bible (Old Testament).

Judaism does not see human beings as inherently flawed or sinful and needful of being saved from it, but rather capable with a free will of being righteous, and unlike Christianity does not closely associate ideas of "salvation" with a New Covenant delivered by a Jewish messiah.

As part of their contribution to support true worship, the ancient Israelites were commanded to donate a tithe, or a tenth, of their annual income. God told them: “You must without fail give a tenth [“tithe,” King James Version] of everything your seed produces in the field year by year.”—Deuteronomy 14:22.
