the king of Arad took some Israelites captive that a non-Jew could acquire an Israelite as a slave by an act of possession. Rav Hanin (or some say Rabbi Hanina) read to show that one who wishes to succeed should set aside some of the gains to Heaven.

For in Achan said, “I have sinned (implying this time), and thus and thus have I done (implying twice apart from this instance).” A Midrash taught that according to some authorities, Israel fought Sihon in the month of Elul, celebrated the Festival in Tishri, and after the Festival fought Og. The Midrash inferred this from the similarity of the expression in "And you shall turn in the morning, and go to your tents," which speaks of an act that was to
