Deuteronomy 24:12-13, 17

If the man is poor, you shall not keep his pledge overnight. You shall certainly restore the pledge (security deposit) to him at sunset, so that he may sleep in his garment and bless you; and it will be credited to you as righteousness (right standing) before the LORD your God.

“You shall not pervert the justice due a stranger or an orphan, nor seize (impound) a widow’s garment as security [for a loan].
