Matthew 5:42
Give to the one who begs from you, and do not refuse the one who would borrow from you.
Psalm 112:5
It is well with the man who deals generously and lends; who conducts his affairs with justice.
But then on the other hand...
Leviticus 25:35-37
If your brother becomes poor and cannot maintain himself with you, you shall support him as though he were a stranger and a sojourner, and he shall live with you. Take no interest from him or profit, but fear your God, that your brother may live beside you. You shall not lend him your money at interest, nor give him your food for profit.
Exodus 22: 25-27
If you lend money to any of my people with you who is poor, you shall not be like a moneylender to him, and you shall not exact interest from him. If ever you take your neighbor's cloak in pledge, you shall return it to him before the sun goes down, for that is his only covering, and it is his cloak for his body; in what else shall he sleep? And if he cries to me, I will hear, for I am compassionate.
Deuteronomy 15: 8-10
But you shall open your hand to him and lend him sufficient for his need, whatever it may be. Take care lest there be an unworthy thought in your heart and you say, The seventh year, the year of release is near, and your eye look grudgingly on your poor brother, and you give him nothing, and he cry to the Lord against you, and you be guilty of sin. You shall give to him freely, and your heart shall not be grudging when you give to him, because for this the Lord your God will bless you in all your work and in all that you undertake.
So heck if I know about what the Bible wants concerning lending. Sounds like we are supposed to be suckers, Lord forgive me.
