The Lord details the individuals and families that worked together over against their own homes to do a great collective work of rebuilding the wall. How was this great task accomplished? By individual families, devoted and committed to rebuilding the portion of the wall next to their own homes. In like manner, we must all take responsibility for our portion of the wall in the kingdom of God, to repair any breaches to where the whole wall is secure and strong against the relentless attacks of Satan.
