Jewish angelic hierarchy is a system of angels in Jewish belief. Angels are thought to be God's helpers and messengers on Earth, doing His work. In the Jewish angelic hierarchy, each angel has a different job and a different level of responsibility. For example, there is an angel in charge of protecting people, another in charge of helping people to understand and follow God's rules, and so on. Each group of angels has its own leader, who is in charge of leading the other angels in their group. In all, there are 10 groups of angels, with each group having its own leader. All of these angels work together to help God carry out His plans on Earth.
