After gossiping about the marriage of Moses, Miriam was struck with illness and her brother offered a short prayer for her: Moshe yelled to the LORD, saying, “God, please, heal her, please.” The Alshikh explains that were Moshe to offer a long prayer, people would say he favored his sister, but if he offered a short prayer Miriam would suspect that his prayer for her lacked sincerity. Therefore Moshe yelled a short prayer – the people would not suspect him of favoring his sister and Miriam would know that the prayer was heartfelt.
