Hebrews

In most modern versions of the New Testament, the Epistle to the Hebrews is given without the author’s name. But the King James Version still follows an old Eastern tradition, and attaches Paul’s name to the Epistle. The Hebrews are the descendants of Abraham. The Hebrews represent the thoughts in man that have come up out of the purely material and passed over to a higher concept of God and of God’s laws, into a closer and clearer relationship with God.
