Deuteronomy 24:12-14

12If the man is poor, you shall not keep his pledge overnight.

13You 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.

14“You shall not take advantage of a hired servant who is poor and needy, whether [he is] one of your countrymen or one of the strangers (resident aliens, foreigners) who is in your land inside your cities.
