Midrasch zu Kohelet 1:5

R. Chiya b. Abba, in the name of R. Jochanan, said: "A righteous man does not depart from the world, till another righteous man like him has been born, as it is said (Ecc. 1, 5) The sun rises, the sun goes down; i.e., before the sum of Eli had been extinguished, the sun of Samuel of Ramah already shone." Again said R. Chiya b. Abba, in the name of R. Jochanan: "The Holy One, praised be He! perceived that the righteous men were few, so He planted them in every generation, as it is said (I Sam. 2, 8) For the Lord's are the pillars of the earth, on which He hath set the world." Again said R. Chiya b. Abba, in the name of R. Jochanan: "Even through the merits of one righteous man, the world can exist, as it is said (Prov. 10, 25) The righteous is the foundation of the world." R. Chiya b. Abba said on his own authority: "We infer it from the following passage (I Sam. 2, 9) He ever guardeth the feet of His pious one." But the Khasidav (pious ones) are spoken of in the plural?" R. Nachman remarked: "It is nevertheless spelled in the singular." R. Chiya b. Abba said further, in the name of R. Jochanan: "When a man has lived the greater part of his life without having sinned, he will sin no more, for it is said (Ib.) He ever guardeth the feet [the end] of His pious ones." At the school of R. Shila it was said: "When a man has had occasion to commit a sin once and twice, and he escapes committing it, he will be guarded thereafter from sinning, as it is said (Ib.) He ever guardeth the feet of His pious ones."

When Rabbi was about to die he said: "There is a town, Humania, in Babylon of which the entire population consists of Ammonites; there is another town by the name of Margaria in Babylon of which the entire town consists of impure children; again there is another town in Babylon by the name of Birka, where there dwell two brothers who exchange their wives with each other; there is another town under the same Fort Destaya (Messima) in Babylon, and today they have turned away from the Lord. They had put out nets and went with them to catch fishes on the Sabbath. R. Achi b. Yashi placed them under a ban and they became converts. There is a town in Babylon named Adra of Agma in which Adda b. Ahaba (Ib. b) is sitting today in the bosom of Abraham (is being circumsized). Today R. Juda has been born in Babylon." For the master said elsewhere: "At the death of R. Akiba, Rabbi was born; at the death of Rabbi, R. Juda was born; at the death of R. Juda, Raba was born; and at the death of Raba, R. Ami was born. This is to teach you that a righteous man does not leave the world until another righteous like him is born, for the passage says (Ecc. 1, 5) The sun also ariseth and the sun goeth down; i.e., before the sun of Illai went down the son of Samuel of Ramath arose, as it is said (I Sam. 3, 3) And the lamp of God had not yet gone out, while Samuel was lying down," etc.

And he shall wave the sheaf before the Lord. How did he wave it? R. Hama b.Ukba in the name of R.Joshua b. Hanania said: He moved it forward and backward, upward and downward; forward and backward to symbolize that the act was in honor of Him to whom the whole world belongs; upward and downward to symbols that the act was in honor of Him to whom belong the regions on high and the regions below. R. Simon son of R. Joshua said: The movements forward and backward were to counteract the effects of injurious winds; and the movements upward and downwards were to counteract the effect of injurious dews.

..."The sun rises and goes down" (Ecclesiastics 1:5). Rabbi Aba bar Kahana said: Don't we know that the sun rises and goes down? Rather (this is what it means): When the Holy One of Blessing causes the sun of a righteous person to set, he causes the sun of his fellow to shine forth. The day that Rabbi Akiba died, our rabbi (Judah the Prince) was born and it was written about him "The sun rises and the sun goes down." On the day that our rabbi died Rabbi Ada Bar Ahava was born and it was written about him "The sun rises and the sun goes down." On the day that Rabbi Ada Bar Ahava died, Rabbi Avin was born and it was written about him "The sun rises and the sun goes down." On the day that Rabbi Avin died, his son Rabbi Avin was born. The day that Rabbi Avin died, Aba Hoshaya from Traya was born. The day that Aba Hoshaya died Rabbi Hoshaya was born and it was written about him "The sun rises and the sun goes down." Before the sun of Moses set the sun of Joshua shone forth as it is written, "God said to Moses, take Joshua Son of Nun" (Numbers 27:18). Before the sun of Joshua set the sun of Itaniel son of Kenaz shone forth as it is said, "Itaniel son of Kenaz took it" (Judges 1:13). Before the sun of Eli the priest set, the sun of Samuel shone forth, "the lamp of God had not yet gone out and Samuel lay on the sanctuary of God" (1 Sam 3:3). Rabbi Yochanan said, "like a perfect calf." Before the God causes the sun of Sarah to set, he causes the sun of Rebecca to shine forth. For first it says "Behold Malkah also bore children" (Gen 22:20) and after "and the life Sarah was one hundred years..."
