An allegorical name applied to Israel by the Deutero-lsaiah (Isa 62:4-5). She was no longer to be a wife deserted by God, as she had been during the Captivity, but married (1) to God, (2) by a strange application of the figure, to her own sons.
You will no longer be called Deserted, and your land will not be called Desolate; instead, you will be called My Delight is in Her, and your land Married; for the Lord delights in you, and your land will be married. For as a young man marries a virgin, so your sons will marry you; and as a bridegroom rejoices over [his] bride, so your God will rejoice over you.
