Contradiction with Hebrews 9:6-10
Exodus 27:21 describes an ongoing practice of maintaining the lamp, whereas Hebrews 9:6-10 implies a transition from the old covenant practices to a more spiritual worship, suggesting the ceasing of the old practices with the coming of Christ.
Hebrews 9:6-10: Now when these things were thus ordained, the priests went always into the first tabernacle, accomplishing the service [of God].

Argues that the law is a shadow of good things to come and the rituals it entails, like those in Exodus 27:21, cannot perfect the worshippers permanently.
Hebrews 10:1-4: For the law having a shadow of good things to come, [and] not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
