Midras Ratapan 3:27: Eikhah Rabbah & Aggadat Bereshit

“The Lord is good to those who trust in Him, to the soul that seeks Him” (Lamentations 3:25).
“The Lord is good to those who trust in Him” – is it, perhaps, to everyone?⁵⁵One might think that the Lord is good to everyone who trusts in Him. The verse states: “To the soul that seeks Him.”⁵⁶This is taken to mean that God is good only to those who seek Him alone and do not place their trust in anything else (Etz Yosef). Similarly, “Truly, God is good to Israel” (Psalms 73:1) – is it, perhaps, to everyone? The verse states: “To those pure of heart” (Psalms 73:1), to those whose heart is pure, who have no iniquity. Similarly, “Happy is the man whose strength is in You” (Psalms 84:6) – is it, perhaps, for everyone? The verse states: “Whose heart follows Your path” (Psalms 84:6), those in whose hearts the path of the Torah is paved. Similarly, “Be good, Lord, to those who are good” (Psalms 125:4) – is it, perhaps, for everyone? The verse states: “And to the upright of heart” (Psalms 125:4). Similarly, “The Lord is close to all who call Him” (Psalms 145:18) – is it, perhaps, for everyone? The verse states: “To all who call Him in truth” (Psalms 145:18). Similarly, “Who is God like You, bearing iniquity and overlooking transgression?” (Micah 7:18) – is it, perhaps, for everyone? The verse states: “For the remnant of His inheritance” (Micah 7:18).
“It is good to wait silently for the salvation of the Lord” (Lamentations 3:26).
“It is good to wait silently for the salvation of the Lord” – Rabbi Shimon ben Lakish said: After the Holy One blessed be He despairs of the righteous in this world, He then has mercy on them. That is what is written: “It is good to wait silently for the salvation of the Lord.”
“It is good for a man that he bear a yoke in his youth” (Lamentations 3:27).
“It is good for a man that he bear a yoke in his youth” – the yoke of Torah, the yoke of a wife, the yoke of labor.

Chapter (60) 61: Torah [1] And Joseph was brought down to Egypt (Genesis 39:1). This is what scriptures say: "Good is the man who sits alone and is silent, for he will bear the yoke upon himself. He will put his mouth to the dust and hope that there may be hope, because the Lord will not cast off forever" (Lamentations 3:27-29). "Good is the man" [who bears the yoke] "in his youth". Blessed is he who accepts suffering in his youth, for his end will be peaceful. Job's friends also said to him: "Why do you complain about the suffering that has come upon you? Rather, your end will be peaceful," as it is said: "Your beginning was small, but your end will be very great" (Job 8:7). The suffering that you are experiencing now will save you from Gehenna (Hell), and you will rest in Gan Eden (Paradise), as it is said: "And he also brought you out of distress into a broad place where there was no constraint" (Job 36:16). This is to save you from the narrow mouth of Gehenna, which is narrow from above but wide from below, as it is said: "The earth is dark and barren, like a shadow" (Job 10:22). The wicked are like birds in Gehenna, because there is no air or land there. Therefore, it is wide and not constrained below, and not only did the suffering that came upon you save you from Gehenna, but you rest in Gan Eden, as it is said: "And your table will be full of fatness" (Job 36:16). Therefore, "Good is the man" [who bears the yoke in youth] and so on. [Pirkei Avot 3:5]
