This is what the Lord said to me: "Go and buy yourself linen underwear and put it on, but don't get it wet."
References for Jeremiah 13:1
So I bought underwear as the Lord instructed me and put it on.
Then the word of the Lord came to me a second time:
"Take the underwear that you bought and are wearing, and go at once to the Euphrates River and hide it in a rocky crevice."
References for Jeremiah 13:4
So I went and hid it by the Euphrates, as the Lord commanded me.
A long time later the Lord said to me, "Go at once to the Euphrates and get the underwear that I commanded you to hide there."
So I went to the Euphrates and dug up the underwear and got it from the place where I had hidden it, but it was ruined-of no use whatsoever.
Then the word of the Lord came to me:
"This is what the Lord says: Just like this I will ruin the great pride of both Judah and Jerusalem.
These evil people, who refuse to listen to Me, who walk in the stubbornness of their own hearts, and who have followed other gods to serve and worship-they will be like this underwear, of no use whatsoever.
Just as underwear clings to one's waist, so I fastened the whole house of Israel and of Judah to Me"-[this is the Lord's declaration]-"so that they might be My people for My fame, praise, and glory, but they would not obey.
