Midrasch zu Schemot 30:29

11) From (Shemoth 29:37): "All that touches the altar shall become consecrated" we learn that the altar consecrates what is appropriate for it. Whence do we derive that even the ramp (leading to the altar) consecrates what is appropriate for the altar? From "eth the altar" ("eth" connoting inclusion). Whence do I derive that even the ministering vessels consecrate what is appropriate for them? From (Shemoth 30:29): "And they (the ministering vessels) shall be holy of holies. All that touches them shall be consecrated."
