Proverbs 4:3

"He taught me also, and said unto me, Let thine heart retain my words: keep my commandments and live."

The "he" in this verse refers back to the father. In verse 1, children are encouraged to hear the instruction of their father. In verse 2 it says fathers give good doctrine (teaching), so it is wise not to go against their instruction. Verse 3 mentions that the father was taught by his father, so we have 3 generations mentioned here.

This all points to the need of families to pass on good teaching, wise counsel, and good character building tools to their children. Wisdom is passed down from generation to generation. It can be assumed that lack of wisdom can also be passed down. Personal influence is the best way to pass along wisdom, whether to your children or someone else in your life.
