The million dollar question

After 120 years, the first thing a person is asked, says the Gemara in Shabbos, is whether he dealt faithfully in business. The word is emunah, not honesty or fairness. Why is money the opening question, and why that word?The same idea sits behind a small puzzle in Parshas Behar. The laws of interest and honest dealing appear next to Shemitah and Yovel, not with the other monetary laws in Mishpatim. The Sefer HaChinuch on Shemitah holds the thread. A man worried about making a living, and a blessing from Rabbi Meir Abuchatzeira, ends in a place he never expected.
