'Pledge' in the Bible
“No one shall take a handmill or an upper millstone [used to grind grain into bread] as security [for a debt], for he would be taking a [person’s] life in pledge.
“When you lend your neighbor anything, you shall not go into his house to get his pledge (security deposit).
You shall stand outside, and the man to whom you lend shall bring the pledge out to you.
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].
