What did Moses do that affected the Israelite's winning?

Moses played a crucial role in the Israelites' victories by leading them out of Egypt and guiding them through the wilderness. He communicated directly with God, receiving the Ten Commandments and divine instructions that shaped their identity and laws. Additionally, during battles, he lifted his hands in prayer, and as long as his hands were raised, the Israelites prevailed. His leadership and faith were pivotal in maintaining the morale and unity of the people, ultimately contributing to their successes.
