Scholars can not be certain of who wrote the letter to the Hebrews. The letter exalts Christ in His superiority.
Letter to the Hebrews 1: 1-4 In times past, God spoke in partial and various ways to our ancestors through the prophets; in these last days, He spoke to us through a Son, Whom He made Heir of all things and through Whom He created the universe, Who is the refulgence of His glory, the very imprint of His Being, and Who sustains all things by His mighty Word. When He had accomplished purification from sins, He took His seat at the right Hand of the Majesty on high, as far superior to the angels as the Name He has inherited is more excellent than theirs.
Letter to the Hebrews 2: 11-12 He who consecrates and those who are being consecrated all have one origin. Therefore he is not ashamed to call them “brothers,” saying, “I will proclaim Your Name to my brothers, in the midst of the assembly I will praise You.”
Letter to the Hebrews 6:10 For God is not unjust so as to overlook your work and the love you have demonstrated for His Name by having served and continuing to serve the holy ones.
Letter to the Hebrews 11: 17-18 By faith Abraham, when put to the test, offered up Isaac, and he who had received the promises was ready to offer his only son, of whom it was said, “Through Isaac descendants shall bear Your Name.”
Letter to the Hebrews 13: 15 Through Him [then] let us continually offer God a sacrifice of praise, that is, the fruit of lips that confess His Name.
