42 Here the measurement was kept in cubits in the translation because of the possible symbolic significance of the number 144 (12 times 12). This is about 216 ft (65 m).
43 Here L&N 81.1 translate the phrase μέτρον ἀνθρώπου, ὅ ἐστιν ἀγγέλου (metron anthrōpou, ho estin angelou) “ ‘the unit of measurement used by a person, that is, by an angel’ Re 21:17.” It is more likely that μέτρον is an accusative of respect or reference.
