Ezekiel 40:32

And he brought me into the inner court toward the east: and he measured the gate according to these measures.

Cross-reference

Ezekiel 40:28-31 describes the south inner gate — the east inner gate here is said to be the same size, confirming symmetry.

Ezekiel 40:35 describes the north inner gate with identical dimensions — all inner gates share the same measurements.

In Ezekiel 40:27, the inner court south gate is measured, confirming the same pattern for this east gate—both are 'same size as the others.'
