Ezekiel 40:16

There were shuttered windows or alcoves in the exterior walls of the guardrooms and vestibule, perhaps creating cupboards for storing the utensils. [Note: Block, The Book . . . 48, p. 523.] Representations of palm trees decorated the doorframes, one on each side of each door (Ezekiel 40:26). Palm trees were symbols of beauty, fruitfulness, salvation, glory, and the millennial age (cf. Leviticus 23:40; 1 Kings 6:29; 1 Kings 6:32; 1 Kings 6:35; 1 Kings 7:36; 2 Chronicles 3:5; Song of Solomon 7:7; Psalms 92:12-14; Nehemiah 8:15; Zechariah 14:16-21).

"The entire gate system resembled the multiple entry gates archaeologists discovered from the Solomonic period. There were several guard rooms (cf. 1 Kings 24 [sic 14]:28; 2 Chronicles 12:11), or alcoves, on either side of the inner part of the Solomonic gate." [Note: Alexander, "Ezekiel," p. 956.]
