2 Kings 4:39-41

39 One of them went out into the fields to gather herbs and found a wild vine. He gathered some of its gourds and filled the fold of his cloak. When he returned, he cut them up into the pot of stew, though no one knew what they were.

40 The stew was poured out for the men, but as they began to eat it, they cried out, “O man of God, there is death in the pot!” And they could not eat it.

41 Elisha said, “Get some flour.” He put it into the pot and said, “Serve it to the people to eat.” And there was nothing harmful in the pot.
