דִּבְרֵ֥י יִרְמְיָ֖הוּ בֶּן־חִלְקִיָּ֑הוּ מִן־הַכֹּֽהֲנִים֙ אֲשֶׁ֣ר בַּעֲנָת֔וֹת בְּאֶ֖רֶץ בִּנְיָמִֽן׃
די װערטער פֿון יִרמיָהו דעם זון פֿון חִלקִיָהון, פֿון די כֹּהנים װאָס אין עַנָתוֹת אין לאַנד בנימין,
Rashi
The words of Koheles. Wherever it is stated, “the words of דִּבְרֵי,” it introduces words or reproof. [For example,] “These are the words הַדְּבָרִים that Moshe spoke,”1Devarim 1:1. [followed by,] “And Yeshurun became fat [and kicked].”2Ibid. 32:15. [Also,] “The words דִּבְרֵי of Amos,”3Amos 1:1. [followed by,] “Hear this word, you cows of Bashan.”4Ibid. 4:1. [Also,] “The words דִּבְרֵי of Yirmiyahu,”5Yirmiyahu 1:1. [followed by,] “Ask now and see whether a male gives birth, etc.”6Ibid. 30:6. [And finally,] “And these are the words דִּבְרֵי of Dovid,”7II Shmuel 23:1. [followed by,] “But the wicked are all like thorns thrust away.”8Ibid. 23:6. “The words דִּבְרֵי of Koheles” [is followed by,] “The sun rises ... All the rivers flow into the sea.”9Below, verse 5. He refers to the wicked as the “sun,” the “moon,”10Below, verse 7. and the “sea,” which earn no reward. So it was taught in Sifre. I learned from there that the section deals with the wicked and he compares them to the rising sun, which ultimately sets. Addendum: Another explanation, “All the rivers flow into the sea.” What is the meaning of this? This is stated concerning idolaters, the fools who prostrate themselves to the water thinking that it has substance because they see the Great Sea, into which all the rivers flow and it is not full, but they have no understanding that to the place where the rivers flow, they repeatedly go, for the water of the rivers that flow into the sea are the very same waters that already flowed; they flow from under the deep and flow above the surface until the sea and then flow again. Therefore, the rivers do not stop, and the sea is not full, and not because they have substance. End of addendum.
Rashi
from Ramah Where he went into exile by himself with them. He would see a group [of youths] joined by a collar and would put his neck between them, etc., as is stated in Pesikta of the Haftarah Divrei Yirmiyahu (p. 113). For it is impossible to say that Nebuzaradan put him in chains since Nebuchadnezzar commanded him, “Do him no harm” (above 39:12).
Ibn Ezra
Aaron denotes the High Priest, who will replace him one of his descendants denotes one of the ordinary kohanim, who can be found outside of the Temple, like the kohanim of ⊂ Anatot [Jeremiah 1:1].
