“Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.”
King James Version (KJV)
10:9 Then said he - in that very instant he subjoined. Lo, I come to do Thy will - To offer a more acceptable sacrifice; and by this very act he taketh away the legal, that he may establish the evangelical, dispensation.
Heb 10:9 Then said he. He said, first, "The Levitical sacrifices do not please God" (Heb 10:8); then he said, second, Lo, I come to do thy will, O God. This is pleasing to God. Hence he taketh away the first, the old covenant with its sacrifices. That he may establish the second, the new covenant inaugurated by complete submission to the will of God.
