Step-by-step explanation:
The tribe of Levi served as the priests among the twelve tribes of Israel. The Levites were descendants of Levi, one of the sons of Jacob. They were responsible for performing religious rituals, offering sacrifices, and maintaining the Tabernacle (a portable sanctuary) and later the Temple. The Levites did not receive a separate land allotment like the other tribes, but had cities scattered throughout the territories of the other tribes.
