Midrash sa Genesis 45:9: Aggadat Bereshit & Bereshit Rabbah

[2] Another interpretation: "And these are the generations of Isaac. The crown of the elders are the children's children, and the glory of children are their fathers. (Proverbs 17:6) There are good children who give a crown to their fathers, and there are wicked children who take the crown from their father, as it says, "And Ham, the father of Canaan, saw..." (Genesis 9:22). But Shem and Japheth covered the nakedness of their father. (Genesis 9:23) Ishmael serves idols, but Isaac, who was the burnt offering of the Lord, gave a crown to his father. These are the generations of Isaac. Reuben, unstable as water... (Genesis 49:4) and Joseph hurried and went up to his father... (Genesis 50:4). Absalom said, "I will strike down the king alone." (2 Samuel 17:1) But Solomon rode on his own mule... (1 Kings 1:33) Hezekiah stood and added to the work, as it says, "And he did what was right in the eyes of the Lord, according to all that David his father had done." (2 Kings 18:3) Be the crown of the elders, children's children. These are the generations of Isaac."

[2] And so all the righteous suffered in their youth and ultimately found comfort. Abraham suffered greatly in his youth, was thrown into a fiery furnace, and was cast out of his father's house. Sixteen kings came against him, and his wife was taken from him by both Pharaoh and Abimelech. He was tested with his only son, Isaac, but in the end found peace, as it says "And Abraham was old, well advanced in age; and the Lord had blessed Abraham in all things" (Genesis 24:1). Isaac also suffered greatly in his youth, as Ishmael took an arrow and tried to kill him. It says, "And Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, playing with her son Isaac" (Genesis 21:9). "Playing" means he took an arrow and tried to kill him. Furthermore, his father Abraham was going to slaughter him, and then famine came, as it says, "Now there was a famine in the land" (Genesis 26:1). Isaac went to Abimelech and became the target of jealousy, as it says, "And the Philistines envied him" (Genesis 26:14). They told him to leave, and he went and settled in Gerar, where he disputed with the shepherds. But ultimately he found comfort, as it says, "Therefore he called it Rehoboth, for he said, 'For now the Lord has made room for us, and we shall be fruitful in the land'" (Genesis 26:22). Similarly, Jacob suffered greatly, as Esau pursued him, and he was enslaved by his sons. He was pursued by Laban and punished through his daughter. His son was sold, and in the end he found peace, as it says, "And Jacob lived in the land of Egypt seventeen years" (Genesis 47:28). Joseph was deeply pained when his brothers despised him, threw him into a pit, sold him into slavery, and he was imprisoned. As it is written, "They afflicted his feet with shackles; iron pierced his soul until his word came to pass and God's word proved him true" (Psalms 105:18-19). Joseph remained silent, as it is written, "He sits alone in silence" (Lamentations 3:28). In the end, he was redeemed, as it is written, "He will not abandon forever, for He desires to show kindness" (Lamentations 3:31). And it is written at the end, "Hurry and go up to my father" (Genesis 45:9).

[4] Another interpretation: "This is about a small city", the house of Joseph, and there are few people there, these are the tribes, as it is said, "Am I not too few for the number of your mercies?" (Genesis 32:11). A great king came to this city, this is Joseph, as it is written "God made me lord" (Genesis 45:8). He built great fortifications around it, and said to them, "You are spies." But a poor and wise man was found in the city, this is Judah, and he was saved, "I will be his surety" (Genesis 43:9). Mankind did not remember him, so they sent a messenger to him, as it is said, "And he sent Judah ahead of him" (Genesis 45:12).
