4 How attractive is sound judgment in the gray-haired, and for the aged to possess good counsel! 5 How attractive is wisdom in the aged, and understanding and counsel in the venerable! 6Rich experience is the crown of the aged, and their boast is the fear of the Lord.7 I can think of nine whom I would call blessed, and a tenth my tongue proclaims: a man who can rejoice in his children; a man who lives to see the downfall of his foes. 8 Happy the man who lives with a sensible wife, and the one who does not plow with ox and ass together. Happy is the one who does not sin with the tongue, and the one who has not served an inferior.

Clement of Alexandria The Instructor 3.3
The more, then, a man hastes to the end, the more truly venerable is he, having God alone as his senior, since He is the eternal aged One, He who is older than all things. Prophecy has called him the Ancient of days; and the hair of His head was as pure wool, says the prophet. And none other, says the Lord, can make the hair white or black. How, then, do these godless ones work in rivalry with God, or rather violently oppose Him, when they transmute the hair made white by Him? The crown of old men is great experience, says Scripture; and the hoary hair of their countenance is the blossom of large experience. But these dishonour the reverence of age, the head covered with grey hairs. It is not, it is not possible for him to show the head true who has a fraudulent head. But you have not so learned Christ; if so be that you have heard Him, and have been taught by Him, as the truth is in Jesus: that you put off, concerning the former conversation, the old man (not the hoary man, but him that is) corrupt according to deceitful lusts; and be renewed (not by dyeings and ornaments), but in the spirit of your mind; and put on the new man, which after God is created in righteousness and true holiness.
