This verse is the only one in Scripture that describes how the Lord’s delight in his people will overflow in his exulting, yes, boasting over them with loud singing. That almighty God should derive delight from his own creation is significant in itself. But that the Holy One should experience ecstasy over the sinner is incomprehensible.
1
17 The LORD your God is in your midst, a mighty one who will save; he will rejoice over you with gladness; he will quiet you by his love; he will exult over you with loud singing.
