Isaiah 62

Isaiah 62:5

For as a young man marries a virgin,
So your sons will marry you;
And as the bridegroom rejoices over the bride,
So your God will rejoice over you.

I'm not quite sure who Isaiah is speaking to here.  At first, I thought it was Jerusalem itself, but people can't marry cities.  Then I thought it was to the inhabitants of Jerusalem, but sons' can't marry parents.

So, who is it speaking to?  I think it is inhabitants of Jerusalem, but with the understanding that the sons will devote themselves to Jerusalem.  Rather than trying to get rich or powerful, they will desire the city's defense and safety.
