The 7 nations. Yerushalmi and Medrash says that Yehoshua sent 3 messages to the Kenanim. The first one — whoever wants to do teshuva and keep the 7 mitsvos should do so, and the Jews won’t harm them. The second one — whoever does not want to do teshuva is given a grace period to leave Eretz Yisroel. The third one — the remaining reshoim (steeped in immorality and avoda zora) are about to be attacked.
