Deuteronomy 15:9-10

Beware that there be not a base 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 give him nought; and he cry unto Jehovah against thee, and it be sin unto thee. Thou shalt surely give him, and thy heart shall not be grieved when thou givest unto him; because that for this thing Jehovah thy God will bless thee in all thy work, and in all that thou puttest thy hand unto.
