In 2 Kings 2:21-22, Elisha goes to a spring of water and throws salt in it, declaring that the water is healed by the word of the Lord. The correct answer, "death nor miscarriage," is supported by the passage as it states that from that point onwards, the water will no longer cause death or miscarriage. This suggests that the water had previously been causing harm or illness, but Elisha's actions and words brought about its healing.
