Take the belt that you have bought, which is on your waist, and arise, go to the Euphrates, and hide it there in a cleft of the rock. So I went, and hid it by the Euphrates, as Yahweh commanded me. It happened after many days, that Yahweh said to me, Arise, go to the Euphrates, and take the belt from there, which I commanded you to hide there. Then I went to the Euphrates, and dug, and took the belt from the place where I had hidden it; and behold, the belt was marred, it was profitable for nothing.
