Ma`asei (Acts) 1:4-8

And meeting with them, He commanded them not to leave Yerushalayim, but to wait for the Promise of the Father, “which you have heard from Me – because Yoḥanan truly immersed in water, but you shall be immersed in the Set-apart Spirit not many days from now.” So when they had come together, they asked Him, saying, “Master, would You at this time restore the reign to Yisra’ĕl?” And He said to them, “It is not for you to know times or seasons which the Father has put in His own authority. But you shall receive power when the Set-apart Spirit has come upon you, and you shall be My witnesses in Yerushalayim, and in all Yehuḏah and Shomeron, and to the end of the earth.
