(Proverbs 30:24 KJV) There be four things which are little upon the earth, but they are exceeding wise:
This seems like a silly observation but in terms of wisdom, size does not matter. You can be “little” (small NASB) (6996a) and be “exceedingly” (2449) “wise” (2450).
It is no guarantee. We have all heard of the Napoleon complex. Children certainly do not qualify regardless of what your local school teacher says. But being short or lacking in physical stature is no limitation to the containment of wisdom.
So? Accept people as they are. Look past the package and evaluate on the contents. You have heard it a million ways. Make that a million and one.
