Barnes' Notes
A man with a measuring line in his hand - Probably the Angel of the Lord, of whom Ezekiel has a like vision. Jerome: "He who before, when he lift up his eyes, had seen in the four horns things mournful, now again lifts up his eves to see a man, of whom it is written, "Behold a man whose name is the Branch" Zechariah 6:12; of whom we read above, "Behold a man riding upon a red horse, and he stood among the myrtle trees, which were in the bottom" Zechariah 1:8. Of whom too the Father saith; He builded My city, "whose builder and maker is God" Hebrews 11:10. He too is seen by Ezekiel in a description like this, "a man whose appearance was like the appearance of brass" Ezekiel 40:3, that is, "burnished and shining as fire, with a line of flax in his hand and a measuring reed" Ezekiel 1:7. The office also seems to be one of authority, not to measure the actual length and breadth of Jerusalem, but to lay down what it should be, (Cyril), "to mark it out broad and very long."
