2 Kings 4:39-40

39One of them went out into the fields to gather herbs and found a wild vine and picked as many of its gourds as his garment could hold. When he returned, he cut them up into the pot of stew, though no one knew what they were.

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