Regarding pagan King Cyrus of Persia:

“I am the Lord, and there is no other;

Besides Me there is no God.

I will gird you, **though you have not known Me;**

That men may know from the rising to the setting of the sun

That there is no one besides Me.

I am the Lord, and there is no other,

The One forming light and creating darkness,

Causing well-being and creating calamity;

I am the Lord who does all these.”

— Isaiah 45:5-7 NASB1995 (Emphasis mine)
