What does Leviticus 24:8 mean?

Every Sabbath, Aaron is supposed to set out the bread in front of the Lord, always keeping it fresh. This is a lasting agreement between God and the Israelites. Leviticus 24:8 - Modern Text Bible

(This verse explains that the bread offering is a regular, ongoing practice, not just a one-time thing. Aaron, as the priest, is responsible for making sure it's done every week as a sign of the people's relationship with God.)
