"It is forbidden for a person to disown or dedicate all his property and thus become a burden on others."
-- Maimonides' Code, Laws of Right Views 5:12 (quoted here)
"Sell that ye have, and give alms; provide yourselves bags which wax not old, a treasure in the heavens that faileth not, where no thief approacheth, neither moth corrupteth. ... So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple."
-- Luke 12:33, 14:33
