Psalm 89

Then you spoke in a vision to your faithful one, and said:
‘I have set the crown on one who is mighty,
I have exalted one chosen from the people.
I have found my servant David;
with my holy oil I have anointed him;
my hand shall always remain with him;
my arm also shall strengthen him.

I have no idea how the Hebrew 'ezer became "set the crown".

In every dictionary to which I have access this is "given help."

But I'm ready to go with it: In helping us God has crowned us, this confirms our identity as sons and daughters of God, this proclaims our role as servant and leader, we are anointed for profound purpose.
