Knowledge has its place, but nothing replaces Wisdom. There is more wealth in the wisdom of the elderly than in the vitality of the young.
Ecclesiastes 12:11-14
1The words of the wise are like goads, their collected sayings like firmly embedded nails given by one shepherd. 12Be warned, my son, of anything in addition to them. Of making many books there is no end, and much study wearies the body.
13Now all has been heard; here is the conclusion of the matter: Fear God and keep his commandments, for this is the duty of all mankind. 14For God will bring every deed into judgment, including every hidden thing, whether it is good or evil.
