And the work of righteousness - That which righteousness produces; or the effect of the prevalence of righteousness on the nation.
Shall be peace - There shall be no internal agitation, and no conflicts with foreign nations.
Quietness and assurance - This is a beautiful description of the happy effect of the prevalence of piety; and it is as true now as it was in the time of Isaiah. True religion would put an end to strifes and litigations; to riots and mobs; to oppressions and tumults; to alarms and robbery; to battle, and murder, and conflict.
