Origen, on Heb 13:8

“Jesus Christ, yesterday, and today; and the same for ever.”

“And if "today" means the whole present age, "yesterday" is probably the bygone age. This what I have understood to be the meaning in the psalm and in Paul's epistle to Hebrews. In the psalm it says: "A thousand years are in your eyes as a yesterday that has passed." Whatever the much talked of millennium means, it is likened to yesterday as opposed to today. And in the apostle writes, "Jesus Christ is the same yesterday and today and forever." No wonder that the whole of an age counts with God as the space of a single day with us, and I think even less.”
