{A hundred and forty and four cubits} (hekaton
tesserakonta tessar(936e) p(8863)h(936e)). Another multiple of 12
(12x12=144) as in  7:4  14:1 . It is not clear whether it is the
height or the breadth of the wall that is meant, though hupsos
(height) comes just before. That would be 216 feet high (cf.
verse  12 ), not enormous in comparison with the 7,000,000 feet
(1500 miles) height of the city. {According to the measure of a
man, that is, of an angel} (metron anthr(9370)ou, ho estin
aggelou). No preposition for "according to," just the accusative
case of general reference in apposition with the verb
emetr(8873)en. Though measured by an angel, a human standard was
employed, man's measure which is angel's (Bengel).
