Deuteronomy 15:9-10

9Beware that there be not a wicked thought in thy 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 against thee to Jehovah, and it be sin in thee.

10Thou shalt bountifully give unto him, and thy heart shall not be evil-disposed when thou givest unto him; because for this thing Jehovah thy 1God will bless thee in all thy works, and in all the business of thy hand.
