Better is a poor and a wise child than an old and foolish king, who will no more be admonished. Eccles 4:13
The Bible speaks in many places about the wisdom of the aged:
A crown of beauty are grey hairs, In the way of righteousness it is found. Proverbs 16:31
You are to rise in the presence of the elderly and honor the old. Fear your God; I am Yahweh." Leviticus 19:32
But it also warns the aged against being stuck in their ways, as it does in the verse from Ecclesiastes.
Although youth must learn to listen to the wisdom of those who are older than they, the aged must also know how to seek counsel.
So Elihu the son of Barachel the Buzite spoke out and said, "I am young in years and you are old; Therefore I was shy and afraid to tell you what I think. "I thought age should speak, And increased years should teach wisdom. "But it is a spirit in man, And the breath of the Almighty gives them understanding.… Job 32:6-8
When intelligence is lacking, the people shall fall, but in the multitude of counsellors there is salvation. Proverbs 11:14
The ability to hear is often honed by those who are humble enough to be willing to hear. Thus humility of spirit often leads to teachableness. An old king is not only old but powerful. As an elder person, he is expected to be wise. And as a king, he is too feared to be advised. Those around such a person do not readily give their opinion. As he ages in his surety of himself, there is a danger as the years continue, that few will attempt to contradict him if he has the wrong opinion of any subject or person. Especially if such a person wields dangerous power.
The old and powerful are in many fields in society. They can be lawyers, doctors, pastors, teachers, merchants, or even politicians. Their effect on those under their control can be detrimental if they do not attempt to put aside the pride of accomplishment that age and long rule has bred in them.
True wisdom does not change but the world changes and some ancient traditions or assumptions that seem tried-and-true may need to be reassessed. Thus, even the aged must learn to listen anew to young counsellors if they are to truly understand the effects of those traditions they have always believed in and expoused. An old leader who understands his need for humility will understand the present time and his past errors, and will be able to formulate a future vision which will greatly help his people.
