When you lend money to someone, don’t enter their house to collect the collateral. You must remain outside, while the person to whom you made the loan brings the collateral out to you. There is a rabbinic discussion whether this verse only prohibits only the creditor from entering the debtor’s home or even an agent of the court. The dominant view is that although an agent of the court can seize collateral from a public area, s/he is not allowed to enter the debtor’s home. This rule ensures that each person, even a debtor, has some private space.
