“…our Saviour, even all of them, but more especially those uttered by the Psalmist; ‘Sacrifice and offering Thou wouldest not; a body Thou hast prepared Me;’ and should refer all such things as these to the son of Abraham.” — editor's note: Ps. xl. 6.

““Burnt-offerings and sacrifices for sin Thou hast had no pleasure in: then I said, Lo I come to do Thy will, O God!” ( Ps. xl. 6, 7 ), and again, “To what purpose do ye bring the incense from Sheba?” ( Jer. vi. 20.)” — the author cites it
