In this week’s parasha, Beha’alotecha, Moses faces the fragility of life as he watches his sister, Miriam, struggle with tzara’at, a dangerous skin disease. Overcome with anguish, Moses cries out to God. His five-word prayer, the shortest recorded in the Torah, beseeches the Holy One: El na r’fa na la (O God, please heal her). God hears, and miraculously Miriam is healed (Numbers 12:1-16). For some, this parasha provides comfort that, indeed, our prayers for healing work. And then there are people like Sarah.
