I accused them, "To the best of our ability, we've been buying back our fellow Jews who had been sold to foreigners. Even now you're selling your fellow countrymen, only for them to be sold back to us!" They kept quiet and never spoke a word. So I said, "What you're doing isn't right! Shouldn't you live in the fear of our God to avoid shame from our foreign enemies? I'm also lending money and grain, as are my fellow-Jews and my servants, but let's not charge interest. So today please restore to them their fields, vineyards, olive orchards, and homes, along with the one percent interest charge that you've assessed them on the grain, wine, and oil." They responded, "We will restore these things, and will assess no interest charges against them. We will do what you are requesting!" So I called the priests and made them take an oath to fulfill this promise. I also shook my robes, and said, "May God shake out every man from his house and his possessions who does not keep this promise. May he be emptied out and shaken just like this." All the assembly said, "Amen!" and praised the LORD. And the people kept their promise.
