So when they had come together, they were asking Him saying, "Lord is it at this time You are restoring the Kingdom to Israel?". He said to them, "It is not for you to know times or epochs which the Father has fixed by His own authority; but you will receive power when the Holy Spirit has come upon you; and you shall be My witnesses both in Jerusalem, and in Judea and Samaria, and even in the remotest part of earth.". And after He had said these things, He was lifted up while they were looking on, and a cloud received Him out of their sight. And as they were gazing intently into the sky while he was going, behold, two men in white clothing stood beside them.
