Methodius of Olympus — on Phil 2:7 (Methodius Discourse VIII. Thekla)

“Now the numbers into which it is divided, when put together, make seven, and one is wanting to its completion, not being in all points harmonious with itself, like six, which has reference to the Son of God, who came from tile fulness of the Godhead into a human life. For having emptied Himself, and taken upon Him the form of a slave, He was restored again to His former perfection and dignity. For He being humbled, and apparently degraded, was restored again from His humiliation and degradation to His former completeness and greatness, having never been diminished from His essential perfection.”
