Be faithful before the Lord and keep the swore word

Joshua 9:16-27
God is not consulted. And Israel cannot draw back from a treaty sealed in friendship (the meal eaten together). The worst they can do is reduce the Gibeonites to salve status.
King Saul, 200 years later, tried to destroy the Gibeonites and Go punished the nation for breaking their word.. King David allowed the Gebeonites to kill seven of Saul's sons to set the matter right.
So Joshua saved them from the Israelites, and they did not kill them. That day he made the Gibeonites woodcutters and water carriers for the assembly, to provide for the needs of the altar of the Lord at the place the Lord would choose. And that is what they are to this day.
How?
Obey the swore words before the Lord, for God is faithful and Holy.
