'Rites' in the Bible

Now those to camp before the tabernacle toward the east, before the Tent of Meeting, toward the sunrise, were to be Moses, and Aaron and his sons, performing the duties of the sanctuary for whatever was required of the Israelites; and the layman (non-Levite) who approached [the sanctuary] was to be put to death.

In this way they became unclean in their practices;They played the prostitute in their own deeds [by giving their worship, which belongs to God alone, to other “gods”].
