This rare adjective appears in Ezekiel's temple vision describing a wall that is 'appropriate' or 'corresponding.' Both the text and interpretation are uncertain—ancient versions diverge widely (Greek reads 'reed,' Latin 'separate'). Some connect it with the preceding 'way,' yielding 'the appropriate way,' while others take it with 'wall.' The root suggests suitability or appropriateness, appearing also in later Hebrew and Aramaic. Given the textual difficulty, some scholars suspect corruption and propose emendations. This exemplifies the challenges in understanding rare technical architectural terms in prophetic visions.
