Numbers 18:3Meaning & Commentary from the Church Fathers

The Levites have been designated to serve as assistants, acting as attendants to the priestly office. They are tasked with the responsibility to 'be on guard for him,' referring specifically to Aaron, 'concerning all the matters of the tabernacle of the congregation, and to safeguard the children of Israel.' This indicates their role in supporting the priests. Aaron, along with his sons, has been assigned oversight of the tabernacle: 'and let them keep' all that pertains to the tabernacle of the congregation, including the inner veil, which symbolizes the sacred and mystical aspects, and everything typical for those who approach the Divine altar. This serves as a representation of Christ, whom the Father has appointed over His household, 'His house being us' (Heb. 3:6).
