2 Kings 4:38-40

38When Elisha returned to Gilgal, there was a famine in the land. As the sons of the prophets were sitting at his feet, he said to his attendant, “Put on the large pot and boil some stew for the sons of the prophets.”

39One of them went out to the field to gather herbs, and he found a wild vine from which he gathered as many wild gourds as his garment could hold. Then he came back and cut them up into the pot of stew, though no one knew what they were.

40And they poured it out for the men to eat, but when they tasted the stew they cried out, “There is death in the pot, O man of God!” And they could not eat it.
