How did Zeus keep Hercules safe from Hera?

Zeus protected Hercules from Hera's wrath by ensuring his safety during his infancy. He placed Hercules in the arms of Hera while she was asleep, intending for her to nurse him and bond with him. However, when Hera awoke and realized the truth, she rejected him, which allowed Hercules to be raised by the mortal woman Alcmene. Furthermore, Zeus provided Hercules with strength and resilience to face the challenges posed by Hera throughout his life.
