Numbers 3:7 defines the Levites' duties in the tabernacle — directly identifying 'those who serve the tabernacle' mentioned in Heb 13:10.

Numbers 3:8 adds further detail on Levitical service, reinforcing the identity of the tabernacle servers referenced in Heb 13:10.

1 Corinthians 9:13 notes that temple servants eat from the altar — the very principle Heb 13:10 uses to contrast those who cannot eat from Christ's altar.

Ezekiel 44:29 grants priests the right to eat sin offerings—contrasting with Hebrews 13:10, where those serving the tabernacle cannot eat from our altar.
