First it was meant to show that these terms are applied to angels and not to humans in Job 5:1 (the LXX says "holy angels"), just as other terms, such as in Job 2:1 the terms "sons of God" also apply to angels and not men. Second, it was meant to reiterate that nowhere in the bible does it say that all those who believe are "holy" or "saints" except those written or influenced by +Paul, such as Acts, making it his personal innovation that no one used before or after him.
Evidently the perspective noted is one that is convinced that
GOD ALMIGHTY—LORD AND CREATOR OF ALL THAT IS
Could not or would not ON HIS OWN AUTHORITY have
DARED
to have chosen to have spoken through Paul anything unique?
Personally, I wouldn’t
DARE
To put ALMIGHTY GOD
In such a tiny tidy little box.
