Over the course of Jewish history, different attitudes have been held towards poverty and wealth. Unlike Christianity, in which some strands have viewed poverty as virtuous and desirable, Jews have generally viewed poverty negatively. Jacobs and Greer assert that "[i]n general, Jewish texts have portrayed poverty as an unjustifiable burden."In contrast to the consistently negative view of poverty, Kravitz and Olitzky describe a rapidly changing attitude towards acceptance of wealth as desirable as the Hebrews transitioned from being nomadic shepherds to farmers, then ultimately to city dwellers.
