Weal (n.)
that which is best for someone or something, the common good.
On Merriam Webster, meaning “a sound, healthy and prosperous state”. I found this word in the passage “the tool, Wind Sand and Stars“, by Antoine de Saint-Exupery.
“to join together for the common weal”.
this sentence now becomes “to join together or the common good”, as weal sounds like a shortening of “well being”,
