Midrash su Giosuè 14:15

7) R. Shimon b. Gamliel says in the name of R. Shimon b. Lakish: And thus is it written (Joshua 11:15) ("And the name of Chevron of yore was the city of Arba [Abraham]), the great man among the Anakim, and the land had rest from war." Men who honored the tzaddik merited that their land rest (from war).

Another matter, “He made everything beautiful in its time” – Rabbi Bon stated two approaches regarding the following. Rabbi Bon said: Abraham was worthy to have been created before Adam, the first man, but the Holy One blessed be He said: If I create Abraham first, if he sins, there will be no one to come to make amends after him. Rather, I will create Adam, and if he sins, Abraham will come after him and make amends.⁴²This is based on the verse: “He made everything beautiful in its time.” Rabbi Bon said another [source for this idea]: It is written: “The greatest man among the giants” (Joshua 14:15).⁴³This is interpreted as a reference to Abraham. Abraham was worthy to have been created first, as it is stated: “The greatest man among the giants.” Why is he called “greatest”? It is because he was worthy to have been created first, but the Holy One blessed be He said: If I create Abraham first, if he sins, there will be no one to come after him to make amends. Rather, I will create Adam, the first man, and if he sins, Abraham will come and make amends after him.
Rabbi Abba bar Kahana said: Some cite a parable; to what is this matter analogous? [It is analogous] to one who had a substantial beam in his residence, in his house. Where would he place it? Would he not place it in the middle of the great hall, so that it would be able to support the beams in front of it and the beams that are behind it? So too, why did the Holy One blessed be He create Abraham our patriarch in the middle? So that he could provide support for the generations that preceded him and the generations that succeeded him. Rabbi Levi said: One brings a proper wife into the house of an improper wife, but one does not bring an improper wife into the house of a proper wife.⁴⁴Similarly, Abraham was created after Adam in order to have a positive impact on the world that Adam had previously tarnished. Had Abraham been created first, Adam would have negated the positive impact that Abraham made on the world.
Rabbi Yehuda ben Rabbi Simon said: Adam the first man was worthy to have had the Torah given through him, as it is stated: “This is the book of the generations of Adam. [On the day that God created man, in the likeness of God He made him]” (Genesis 5:1).⁴⁵The midrash interprets the “book” in the verse as a reference to the Torah. The Holy One blessed be He said: Adam is my handiwork, will I not give him the Torah so that he may toil in it? Then He said: If six mitzvot were given him and he was unable to keep them and observe them, were I to give him six hundred and thirteen mitzvot – two hundred and forty-eight positive commandments and three hundred and sixty-five prohibitions – all the more so will he not keep them. That is why it is written: “He said to Adam [la’adam]” (Job 28:28) – not Adam [lo adam], I will not give them to Adam. To whom will I give them? I will give them to his descendants.
Rabbi Yaakov of Kefar Ḥanan said: Adam the first man was worthy of having twelve tribes emerge from him, as it is written: “This [zeh] is the book of the generations of Adam” (Genesis 5:1) – zayin – seven, heh –five, twelve tribes, this is the numerical value of “zeh is the book of the generations of Adam.” The Holy One blessed be He said: Adam is My handiwork, will I not give him twelve tribes? He then said: If I gave him two sons and one rose and killed his brother, had I given him twelve sons, all the more so. That is why it written: “He said to Adam [la’adam]” (Job 28:28), not Adam [lo adam], I will not give them to Adam. To whom will I give them? I will give them to Jacob the righteous.
Rabbi Yitzḥak said: At the time when they departed from Egypt, The Israelites were worthy for the Torah to have been given to them immediately, but the Holy One blessed be He said: The radiance of My children has not yet come; they have emerged from the enslavement of mortar and bricks and cannot receive the Torah immediately. To what is this matter comparable? [It is comparable] to a king whose son arose from his illness and they said to him: ‘Let your son go to his academy.’ He said: ‘The radiance of my son has not yet come; rather, let him be indulged for two or three months with food and drink and recover, and then he will go to his academy.’ So too, the Holy One blessed be He said: ‘The radiance of my children has not yet come, they have emerged from the enslavement of mortar and bricks, and I will give them the Torah? Rather, let My children be indulged for two or three months with manna, a spring, and quails, and then I will give them the Torah.’ When? In the third month.
Rabbi Beivai, Rabbi Aivu, and Rabbi Huna said in the name of Rabbi Yitzḥak bar Maryon: At the time when they departed from Egypt, the Israelites were worthy to enter the Land immediately, but the trees were ancient, from the days of Noah. The Holy One blessed be He said: Shall I bring the Israelites into a wasteland? Rather, I will take them on a circuitous path through the wilderness for forty years so that the Canaanites will rise and chop down the old ones and plant new ones, so [the Israelites] would enter the land and find it filled with blessings.
Rabbi says: Even for matters of transgression it is “beautiful in its time.”⁴⁶“He made everything beautiful in its time” alludes to the fact that even the effect of a transgression is influenced by its timing.
