John Gill Commentary Jeremiah 13:6

"And it came to pass after many days, that Jehovah said unto me, Arise, go to the Euphrates, and take the girdle from thence, which I commanded thee to hide there." — Jeremiah 13:6 (ASV)

And it came to pass after many days

When the girdle had lain long in the hole, by the side of Euphrates; this denotes the length of the Babylonish captivity, which was seventy years:

that the Lord said unto me, arise, go to Euphrates, and take the girdle from thence, which I commanded thee to hide there;

which may denote the return of these people from captivity, according to the prophecy of Jeremiah; see (Jeremiah 25:11Jeremiah 25:12) , though this seems to be visionally done, in order to express the wretched state and condition these people were in; either before the captivity, which was the cause of it; or at their return from it, when they were no better for it.
