Deuteronomy 15:3

3 You may collect what a foreigner owes you, but you must not collect what any of your own people owe you.

Deuteronomy 15:3 In-Context

1 "At the end of every seventh year you are to cancel the debts of those who owe you money.
2 This is how it is to be done. Each of you who has lent money to any Israelite is to cancel the debt; you must not try to collect the money; the Lord himself has declared the debt canceled.
3 You may collect what a foreigner owes you, but you must not collect what any of your own people owe you.
4 "The Lord your God will bless you in the land that he is giving you. Not one of your people will be poor
5 if you obey him and carefully observe everything that I command you today.
