So why would one part of Isaiah 60 be poetic and another literal??
Do you think this is poetic too??
Isaiah 60 :
10 "Foreigners will rebuild your walls,
and their kings will serve you.
Though in anger I struck you,
in favor I will show you compassion.
4 "Lift up your eyes and look about you:
All assemble and come to you;
your sons come from afar,
and your daughters are carried on the arm.
5 Then you will look and be radiant,
your heart will throb and swell with joy;
the wealth on the seas will be brought to you,
to you the riches of the nations will come.
12 For the nation or kingdom that will not serve you will perish;
it will be utterly ruined.
This is yet to be fulfilled but seems quite literakl would you not say??
14 The sons of your oppressors will come bowing before you;
all who despise you will bow down at your feet
and will call you the City of the LORD,
Zion of the Holy One of Israel.
