Isaiah 54:6

6.For as a woman forsaken. He meets a doubt which might arise in the minds of believers amidst so distressing a calamity. It seemed as if the Lord had rejected them, so that they had nothing to look for but destruction. The Prophet therefore reminds them that they ought not to despair, because they have been thus forsaken; for God, according to his mercy, is ready to be reconciled, and is even willing to raise them from the dead. (65)

And a wife of youth. He employs this expression in order that, by this metaphor, he may more fully confirm their hearts in that hope; for the hearts of young husbands are more easily reconciled than the hearts of older husbands, being attracted, and, as it were, driven forward by youthful age and tender love. In like manner, he shows that God will be easily reconciled. “True, thou wast divorced; but the divorce shall not be of long duration. The Lord will show himself ready to be reconciled, and will even, of his own accord, be the first to invite thee to reconciliation.” (66)
