God had commanded that Jerusalem be rebuilt; the vision of the measuring of the city was an assurance that He would give comfort and strength to His afflicted ones, and fulfill to them the promises of His everlasting covenant. His protecting care, He declared, would be like "a wall of fire round about;" and through them His glory would be revealed to all the sons of men. That which He was accomplishing for His people was to be known in all the earth. "Cry out and shout, thou inhabitant of Zion: for great is the Holy One of Israel in the midst of thee." Isaiah 12:6.

Gud havde befalet, at Jerusalem skulle genopbygges. Synet om byens opmåling var en forsikring om, at han ville trøste og styrke sit plagede folk og opfylde sin evige pagts løfter på dem. Han sagde, at hans beskyttende omsorg ville være som "en ildmur omkring det", og at han ville åbenbare sin herlighed for alle mennesker gennem dem. Hele jorden skulle få kendskab til det, som han gjorde for sit folk. "Bryd ud i fryderåb, Zions beboere, thi stor i eders midte er Israels Hellige!" Es. 12,6.
