Ezekiel 41:8

I saw also the height of the house round about: the foundations of the side chambers were a full reed of six great cubits.

Cross-reference

Ezekiel 40:5 introduces the measuring rod of six cubits — the same standard used for the platform foundation here.

Ezekiel 43:13 Related theme

Ezekiel 43:13 also uses the cubit measure for the altar — same temple measuring system.
