Deuteronomy 15:8-9

8but you shall open your hand wide to him and willingly lend him sufficient for his need, whatever he needs.

9Beware lest there be a wicked thought in your heart, saying, ‘The seventh year, the year of release, is at hand,’ and your eye be evil against your poor brother and you give him nothing, and he cry out to the Lord against you, and it become sin among you.
