Deuteronomy 15:8-9

8But thou shalt open thine hand wide unto him, and shalt surely lend him sufficient for his need, in that which he wanteth.

9Beware that there be not a thought in thy wicked heart, saying, The seventh year, the year of release, is at hand; and thine eye be evil against thy poor brother, and thou givest him nought; and he cry unto the Lord against thee, and it be sin unto thee.12
