God promised abraham that he would make his descendents into a great nation. God also said that Abraham would become famous and he would be a blessing to others.
We want a king
Abrahams descendents became slaves in egypt, god told moses to lead them out of egypt and take them to the promesed land of israel.
Finally they got to gods promised land but they chose not to live gods way, instead they worshiped other gods.
one day the people of Israel decided they wanted a king , god warned them that having a human king is not a good idea , but they insist, so god gives them one. His name was king david
Most kings after king david didnt live gods way, they lead the people of israel to not live gods way aswell. God tried to tell them to turn back to him otherwise they would be sent away from the promised land.
The enemies invaded israel and wiped it out. Some of gods people managed to return to the promised land and started rebuilding it but it wasnt as good as before.
