Deuteronomy 15:9-10

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 Yhwh against thee, and it be sin unto thee.12

10Thou shalt surely give him, and thine heart shall not be grieved when thou givest unto him: because that for this thing Yhwh thy God shall bless thee in all thy works, and in all that thou puttest thine hand unto.
