2 Kings 4:39-40
39-40One of the men went out into the field to get some herbs; he came across a wild vine and picked gourds from it, filling his gunnysack. He brought them back, sliced them up, and put them in the stew, even though no one knew what kind of plant it was. The stew was then served up for the men to eat. They started to eat, and then exclaimed, "Death in the pot, O man of God! Death in the pot!" Nobody could eat it.
Elisha ordered, "Get me some meal." Then he sprinkled it into the stew pot.
41"Now serve it up to the men," he said. They ate it, and it was just fine— nothing wrong with that stew!
