Sing, O heavens; and be joyful, O earth; and break forth into singing, O mountains: for the LORD has comforted his people, and will have mercy upon his afflicted.
Read Chapter 49
Cyril of Alexandria
We say that those humble ones who submit their necks to Christ and who do not despise the yoke of a kingdom under him, in that they welcome faith, will be fit to worship him in spirit and in truth. [They will] fulfill the worship of those who did not receive faith, those who were not humble but raised their proud horns in the air and spoke unrighteousness against him and his holy prophecies and who exulted in stretching out the neck of their understanding. These were not worthy of spiritual consolation, for they were not deserving. “For what share has faith with unbelief?” as it is written. - "Commentary on Isaiah 18.104.22.168"
