Didaskalia De nobili dicto Davidis

he does not grow sluggish; but even if his outward man is corrupted, the inward man is renewed day by day (2 Cor. 4:16). And the righteous mortify their earthly members: nor do they offer their members as arms of unrighteousness to sin, but offer themselves to God as those who are alive from the dead, and their members as arms of righteousness to God (Col. 3:5; Rom. 6:13).

If it is true what Pliny wrote in book 16, chapter 11, the power of the Cedar is so great that in Egypt the bodies of the dead are preserved when smeared with it.

But righteous men, who are assimilated to Cedars, although they do not possess such a faculty in themselves, nevertheless drink most abundantly from the fullness of Jesus Christ, the water of life springing up into eternal life, and they attribute to Him the immortality of the soul and the resurrection of the body.

The third exornation is derived from the circumstances, of which it is treated in this saying: "Planted in the house of Jehovah; they shall flourish in the courts of our God."

The Prophet speaks of that house of the great King, concerning which the Apostle says: "That thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth" (1 Tim. 3:15).

And although outside the house of Jehovah and the court of the Church we sometimes see wicked men raging, and extending themselves like trees that are spreading, yet, not only do they lose the honor of their esteem, like the Service-tree in the phyllopoiia leaf-fall/shedding of leaves, but they also pass away so quickly that no traces of them remain (Ps. 37:35-36).

The righteous, however, are like trees planted by the rivers of water, that bring forth their fruit in his season: their leaf also shall not wither: and whatsoever they do shall prosper (Ps. 1:3).
