What did Jesus promise the Twelve disciples about ruling?

Les teaches that Jesus had promised the Twelve they would indeed rule the twelve tribes of Israel from Jerusalem under His authority when the kingdom would be set up. The Lord left it that they would rule the twelve tribes when the kingdom is set up and the earth is regenerated back like it would be in the Garden of Eden. So they were pumped up and had a lot to look forward to. In Acts, after Christ had been crucified, buried, and risen from the dead, He had spent 40 days with them in His resurrected body and was about to ascend from the Mount of Olives with the Eleven, since Judas was gone. The Twelve's big concern was whether He was about to restore the kingdom.
