2 Kings 4:38-40

38And Elisha came again to Gilgal when there was a famine in the land. And as the sons of the prophets were sitting before him, he said to his servant, "Set on the large pot, and boil stew for the sons of the prophets."

39One of them went out into the field to gather herbs, and found a wild vine and gathered from it his lap full of wild gourds, and came and cut them up into the pot of stew, not knowing what they were.

40And they poured out some for the men to eat. But while they were eating of the stew, they cried out, "O man of God, there is death in the pot!" And they could not eat it.
