4 "Take the linen loincloth you are wearing, and go to the Euphrates River. Hide it there in a hole in the rocks." 5 So I went and hid it by the Euphrates as the Lord had instructed me. 6 A long time afterward the Lord said to me, "Go back to the Euphrates and get the loincloth I told you to hide there." 7 So I went to the Euphrates and dug it out of the hole where I had hidden it. But now it was rotting and falling apart. The loincloth was good for nothing. 8 Then I received this message from the Lord : 9 "This is what the Lord says: This shows how I will rot away the pride of Judah and Jerusalem.
Matthew Henry's Commentary on Jeremiah 13:4-9
Commentary on Jeremiah 13:1-11
(Read Jeremiah 13:1-11)
It was usual with the prophets to teach by signs. And we have the explanation, verses 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.
