How did the practices of ancient israelites set them apart from other ancient peoples?

Explanation:  Israelis are the first people to officially adopt the belief and worship of one God. Based on this commitment, all other religious and civil laws follow. This means that the religious service,  the relation to the divine, the mutual human relations and the laws are aligned with the predominant belief in one God. On the basis of such laws, the behavior of people, their obligations, purification rituals, marriage, family are determined, everything is subordinated to religious orientation. In this sense, there are differences with other ancient peoples, who believed in many gods, and therefore their system of religiosity, religious and social relations were completely different.
