Luke 4:25-27

25But in truth I say to you, there were many widows in Israel in the days of Elijah, when the sky was closed up for three years and six months, when a great famine came over all the land;

26and yet Elijah was not sent [by the Lord] to a single one of them, but only to Zarephath in the land of Sidon, to a woman who was a widow.

27And there were many lepers in Israel in the time of Elisha the prophet; and not one of them was cleansed [by being healed] except Naaman the Syrian.”
