Repeated (Isa 57:21). All the blessings just mentioned (Isa 48:21) belong only to the godly, not to the wicked. Israel shall first cast away its wicked unbelief before it shall inherit national prosperity (Zac 12:10-14; Zac 13:1, Zac 13:9; Zac 14:3, Zac 14:14, Zac 14:20-21). The sentiment holds good also as to all wicked men (Job 15:20-25, Job 15:31-34). Messiah, as the ideal Israel (Isa 49:3), states the object of His mission, His want of success for a time, yet His certainty of ultimate success. Next: Isaiah Chapter 49
