“6 When they therefore had come together, they asked of Him, saying,
“Lord, wilt Thou at this time restore again the kingdom to Israel?”
7 And He said unto them,
“It is not for you to know the times or the seasons which the Father hath put in His own power.

and in all Judea and in Samaria, and unto the uttermost part of the earth.””
(Acts 1:6-8 KJ21)
