2 Kings 4:38-40

38Afterward Elisha returned to Gilgal. Now there was famine in the land. As the sons of the prophets were sitting before him, he said to his servant, “Put on the large pot and boil stew for the sons of the prophets.”

39Then one of them went out into the field to gather herbs, found a wild vine and picked from it a lapful of wild gourds. Then he came back and sliced them into the stew pot, for they didn’t know what they were.

40Then they served it for the men to eat. But it came to pass as they were still eating the stew, they cried out and said, “O man of God, there is death in the pot.” So they could not eat it.
