21 Then you will think to yourself, 'Who has given me all these descendants? For most of my children were killed, and the rest were carried away into exile. I was left here all alone. Where did all these people come from? Who bore these children? Who raised them for me?'"
Matthew Henry's Commentary on Isaiah 49:21
Commentary on Isaiah 49:18-23
(Read Isaiah 49:18-23)
Zion is addressed as an afflicted widow, bereaved of her children. Numbers flock to her, and she is assured that they come to be a comfort to her. There are times when the church is desolate and few in number; yet its desolations shall not last for ever, and God will repair them. God can raise up friends for returning Israelites, even among Gentiles. They shall bring their children, and make them thy children. Let all deal tenderly and carefully with young converts and beginners in religion. Princes shall protect the church. It shall appear that God is the sovereign Lord of all. And those who in the exercise of faith, hope, and patience, wait on God for the fulfilment of his promises, shall never be confounded.
