Jeremiah 13:2

Thus saith the LORD unto me, Go and get thee a linen girdle, and put it upon thy loins, and put it not in water.

And the word of the LORD came unto me the second time, saying,

Take the girdle that thou hast got, which is upon thy loins, and arise, go to Euphrates, and hide it there in a hole of the rock.

So I went, and hid it by Euphrates, as the LORD commanded me.
