Acts 1:6-8 NLT

6 When the apostles were with Jesus, they kept asking him, "Lord, are you going to free Israel now and restore our kingdom?"
7 "The Father sets those dates," he replied, "and they are not for you to know.
8 But when the Holy Spirit has come upon you, you will receive power and will tell people about me everywhere -- in Jerusalem, throughout Judea, in Samaria, and to the ends of the earth."
