Hebrews 10:18 - Coke's Commentary on the Holy Bible

Now where remission of these is,— The inference here drawn depends upon the preceding words cited from the prophet. See Jeremiah 31:33-34. The apostle quotes here only what was necessary to his purpose, in order to make good his inference; that where there is forgiveness of iniquity, and a promise for the faithful not to remember sins any more, there can be no occasion for any further oblation for sins.
