Hebrews 10:7

Then I said, ‘Here I am, it is written about Me in the scroll: I have come to do Your will, O God.’”

Note Psalms 40:6–8 (see also LXX)

Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.

Then I said, ‘Behold, I have come (in the scroll of the book it is written of me) to do your will, O God.’”

Then said I, Lo, I am come (In the roll of the book it is written of me) To do thy will, O God.
