2 Kings 4:39-40

39Then one 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 sliced them into the pot of stew, for they did not know what they were.

40So they poured it out for the men to eat. And as they were eating of the stew, they cried out and said, “O man of God, there is 1death in the pot.” And they were unable to eat.
