Acts 1:4-6

And while being in their company and eating with them, He commanded them not to leave Jerusalem but to wait for what the Father had promised, Of which [He said] you have heard Me speak. [John 14:16, 26; 15:26.] For John baptized with water, but not many days from now you shall be baptized with (placed in, introduced into) the Holy Spirit. So when they were assembled, they asked Him, Lord, is this the time when You will reestablish the kingdom and restore it to Israel?
