Ezekiel 41:25

And there were made on them, on the doors of the temple, cherubims and palm trees, like as were made upon the walls; and there were thick planks upon the face of the porch without.

Cross-reference

Ezekiel 41:16-20 describes cherubim and palm trees carved on the walls; 41:25 says the doors have the same design.

1 Kings 7:36 also depicts cherubim and palm trees carved on temple furnishings, matching the door decorations here.
