Take the sash that thou hast bought, which is upon thy loins, and arise, go to {a} Euphrates, and hide it there in a cleft of the rock.

(a) Because this river was far from Jerusalem, it is evident that this was a vision, by which it was signified that the Jews would pass over the Euphrates to be captives in Babylon, and there for length of time would seem to be rotten, although they were joined to the Lord before as a girdle about a man.

Jamieson-Fausset-Brown Bible Commentary

4. Euphrates-In order to support the view that Jeremiah's act was outward, Henderson considers that the Hebrew Phrath here is Ephratha, the original name of Beth-lehem, six miles south of Jerusalem, a journey easy to be made by Jeremiah. The non-addition of the word "river," which usually precedes Phrath, when meaning Euphrates, favors this view. But I prefer English Version. The Euphrates is specified as being near Babylon, the Jews future place of exile.

hole-typical of the prisons in which the Jews were to be confined.

the rock-some well-known rock. A sterile region, such as was that to which the Jews were led away (compare Isa 7:19) [Grotius].

Matthew Henry's Concise Commentary

13:1-11 It was usual with the prophets to teach by signs. And we have the explanation, ver. 9-11. The people of Israel had been to God as this girdle. He caused them to cleave to him by the law he gave them, the prophets he sent among them, and the favours he showed them. They had by their idolatries and sins buried themselves in foreign earth, mingled among the nations, and were so corrupted that they were good for nothing. If we are proud of learning, power, and outward privileges, it is just with God to wither them. The minds of men should be awakened to a sense of their guilt and danger; yet nothing will be effectual without the influences of the Spirit.
