(63) Thou shalt bind a stone to it.--The meaning of the symbolic act, which has its parallel in the girdle of Jeremiah 13:1-7, in the potter's vessel of Jeremiah 19:10, and in the yokes of Jeremiah 27:2, is explained in the following verse. The parchment roll by itself might have floated, and been picked up and read, and so the stone was tied to it that it might sink at once, and thus prefigure the destruction of the city. (Compare the reappearance of the symbols in Revelation 18:21, in connection with the destruction of the mystical Babylon.)

51:59-64 This prophecy is sent to Babylon, to the captives there, by Seraiah, who is to read it to his countrymen in captivity. Let them with faith see the end of these threatening powers, and comfort themselves herewith. When we see what this world is, how glittering its shows, and how flattering its proposals, let us read in the book of the Lord that it shall shortly be desolate. The book must be thrown into the river Euphrates. The fall of the New Testament Babylon is thus represented, Re 18:21. Those that sink under the weight of God's wrath and curse, sink for ever. Babylon, and every antichrist, will soon sink and rise no more for ever. Let us hope in God's word, and quietly wait for his salvation; then we shall see, but shall not share, the destruction of the wicked.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.
