And for his diet, there was a continual diet given him of the king of Babylon, every day a portion until the day of his death, all the days of his life.

And for his diet a continual provision was allowed him by the king of Babylon, every day a portion, until the day of his death, all the days of his life.

And for his food there was a continual diet given him of the king of Babylon, every day a portion until the day of his death, all the days of his life.

And his allowance, a continual allowance, hath been given to him by the king of Babylon, the matter of a day in its day, till the day of his death, all days of his life.

And for his food, the king gave him a regular amount every day till the day of his death, for the rest of his life.

And for his meals, a continual provision was allotted to him by the king of Babylon, a measure for every single day, until the day of his death, all the days of his life.

Et portio ejus, portio perpetua dabatur ei a rege Babylonis, per singulos dies ejus, usque ad diem quo mortuus est, omnibus diebus vitae ejus.

And - there was a continual diet given him - This was probably a ration allowed by the king for the support of Jehoiachin's household. For other particulars, see the note on 2-Kings 25:30.
All the days of his life - I believe these words have been by mistake added from the preceding verse. There, they are proper; here, they are tautological. They are wanting in the Septuagint and in the Arabic.
The preceding words, עד יום מותו ad yom motho, "to the day of his death," are wanting in two of De Rossi's and one of Kennicott's MSS.
Coverdale ends thus: - All the days of his life until he died. This is better than the common Version.
Immediately after this verse my old MS. Bible adds the following words: And done is aftir that into caitifte is brougt Israel, and Jerusalem is bestroide, satte Jeremye the prophet weepund, and weiled with this lamentation Jerusalem; and with bitter inwit sighand and criand weilawai, seide. Then follows in red letters: Here beginneth the Lamentation of Jeremye, that is intitle Cenoth; with the sortynge out of Ebrue letters.
Aleph: How sitteth aloon the city, etc. See something of a similar kind from other authorities, at the beginning of Lamentations.

And [for] his food, there was a (q) continual diet given him of the king of Babylon, every day a portion until the day of his death, all the days of his life.
(q) That is he had allowance in the court, and thus at length he had rest and quietness because he obeyed Jeremiah the Prophet, while the others were cruelly ordered that would not obey him.

And for his diet, there was a continual diet given him of the king of Babylon,.... This seems to design not food only, and for himself, which he had daily at the king's table, but all necessary provisions for himself, family, and servants:
every day a portion, until the day of his death, all the days of his life; that is, of Jeconiah's; how long he lived after this is not known; he was now fifty five years of age, and cannot be thought to have lived a great while after, having been imprisoned so many years; and it is certain he did not live to the return from the captivity. Of the death of Zedekiah we have no account, only that he died in prison. The Jews say (x) he died at this very time, when Jeconiah was advanced. The account here given of Jeconiah has led some to conclude that this chapter was not written by Jeremiah; since it cannot be well thought he should live so long as to the death of this prince; and, besides, had given an account of the destruction of Jerusalem in the thirty ninth chapter, which he would hardly repeat: though that he might do, partly for the sake of new circumstances here added; and partly as an introduction to the book of the Lamentations, which follows.
(x) Seder Olam Rabba, c. 28. p. 81.

every day a portion--rather, "its portion," (compare 1-Kings 8:59, Margin).

All the days of his life - Here ends the history of the kingdom of Judah. I shall only observe the severe judgment of God upon this people, whose kingdom was made up of the two tribes of Judah and Benjamin, and half the tribe of Manasseh. In the numbering of the persons belonging to these two tribes, Numbers 1:27, Numbers 1:35, Numbers 1:37, (counting half of the number of the tribe of Manasseh) we find one hundred twenty - six thousand one hundred: Numbers 26:22, Numbers 26:34, Numbers 26:41, we find of them one hundred forty - eight thousand four hundred and fifty. Here, Jeremiah 52:30, we find no more of them carried into captivity, than four thousand and six hundred. From whence we may judge what a multitude of them were slain by the sword, by the famine, and pestilence! It is a dreadful thing to fall into the hands of the living God, to mock his messengers, despise his words, and misuse his prophets, 'till there be no remedy, 2-Chronicles 36:16.
