In the next scene of his vision, Zechariah saw a man (i.e, an angel who looked like a man) with a measuring line in his hand (cf. Zechariah 1:11; Zechariah 6:12; Ezekiel 40:2-3). When the prophet asked him where he was going, he replied that he was going to measure the dimensions of Jerusalem. This surveying would have been preparation for restoring and rebuilding the city. The restoration of Jerusalem in progress in Zechariah"s day was only a foreview of a much grander future restoration to be described (cf. Jeremiah 32:15; Ezekiel 40:3; Ezekiel 40:5; Revelation 11:1).
