[Harmless Teddy Bear]

Read the story. Other people drew water but the Gibeonites had to do it if the temple needed water. They did not have a right to draw water but the obligation to do it.

Saul tried to wipe them out during his reign which also argues against your premise.

[muawiyah]

Not to argue with you but there's not enough information provided to demonstrate that a "water drawing" caste didn't have the same sort of monopoly all other such castes have had down through the ages in all other human societies.

It's kind of like the members of the French nobility who vied to have the honor of taking King Louis' night soil out of his chambers. It meant that every day they would have ACCESS to the King himself right in the morning when he was fresh and before others could tell him gossip about themselves!

Sure, both of us would have been in there begging to be allowed to draw water for the Temple, particularly the Chief Priest!
