It’s literally ancient.
From the Old Testament book of Isaiah: “Holy, holy, holy is the LORD God Almighty.”
Missed the edit window, but here is the exact quote:
*Above him were seraphs, each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying. And they were calling to one another:
“Holy, holy, holy is the LORD Almighty;
the whole earth is full of his glory.” *
- Isaiah 6:2-3
