Jeremiah 51:63 Meaning and Commentary

Jeremiah 51:63

And it shall be, when thou hast made an end of reading this
book
To the captive Jews; and having also said the above words by way of prayer and approbation: [that] thou shalt bind a stone to it, and cast it into the midst of
Euphrates;
a river by which Babylon was situated. The book, being read, was to be rolled up again, and then a stone tied to it, and cast into the middle of the river, where the waters were deepest, and from whence it could not be taken up; and this was a sign confirming the above prophecy; compare with this what was done by a mighty angel concerning mystical Babylon, in which there is an allusion to this, ( Revelation 18:21 ) .

Jeremiah 51:63 In-Context

61 And Jeremiah said to Seraiah, When you come to Babylon, see that you give them all these words;

62 And after reading them, say, O Lord, you have said about this place that it is to be cut off, so that no one will be living in it, not a man or a beast, but it will be unpeopled for ever.

63 And it will be that, when you have come to an end of reading this book, you are to have a stone fixed to it, and have it dropped into the Euphrates:

64 And you are to say, So Babylon will go down, never to be lifted up again, because of the evil which I will send on her: and weariness will overcome them. So far, these are the words of Jeremiah.
