Midrash su Giosuè 10:1

It is written: "and I gave the plague of Tzaraat” (Vayikra 14:34) Rabbi Hiya learned - and is this [good] news for them that a plague will come upon them? Rabbi Shimon son of Yohai learned since the Canaanites heard that Yisrael were coming upon them, they got up and they hid their money in their houses and in their fields . The Holy One Blessed Be He [Hash-m] said "I promised to your forefathers that I would enter their children to a land full of good" as it is said (Devarim 6:11) “ and houses full of good.” What did Hash-m do? He sent plagues in their houses [of Jews who settled in Israel] - and he [the owner of the house] would break it down and he would find there a treasure. And who was the one who told the Canaanites that Israel was entering into the land? Rabbi Yishmael son of Nah'man said "there are three ultimatums that Yoshua / Joshua sent to them [to the nations that were in Israel at the time he was about to conquer it] the one who wishes to leave, may leave. The one who wishes to make peace [by committing to observe the 7 Noahide laws], may make peace. And the one who wishes to make war, let them do so. The Girgashi [nation] stood up and left - the country] therefore He [Hash-m] gave him a land beautiful like His [Hash-m’s] land [Israel]. This is what is written (Yeshaya 36:17) “ until I came and I took you to the land like your land" - this is Africa [Some Say the Girgashi Went to Morocco - which is a beautiful land]. The Givonim made peace as it says (Yehoshua 10:1) “ and when the settlers of Gibon made peace…”. Thirty-one kings waged war and fell.

And Malchitzedek king of Shalem – This is what is written “And the daughter of Tyre shall seek your presence with tribute, those who are the richest of the people.” (Tehillim 45:13) ‘Malchitzedek the king of Shalem’, this place makes its inhabitants righteous (matzdik) – Malchitzedek, Adonitzedek (Yehoshua 10:1). Jerusalem is called righteousness as it says, “…in which righteousness would lodge…” (Isaiah 1:21) ‘king of Shalem’ R’ Yitzchak the Bavli says (he is called this) because he was born circumcised. "brought out bread and wine, and he was a priest to the Most High God" (Bereshit 14:18) R’ Shmuel bar Nachmani and the Rabbanan argue, R’ Shmuel said that the laws of the High Priesthood were revealed to him – ‘bread’ is the show bread, ‘wine’ are the libations. The Rabbanan say that Torah was revealed to him as it says, “"Come, partake of my bread and drink of the wine I have mingled.” (Mishle 9:5) ‘and he was a priest to the Most High God’ R’ Aba bar Kahana said every mention of wine written in the Torah makes an impact except for this, R’ Levi said that even this we did not escape, because from there He called upon him “…and they will enslave them and oppress them, for four hundred years.” (Bereshit 15:13)
