Acts 1:6 (ESV)

6 So when they had come together, they asked him, “Lord, will you at this time restore the kingdom to Israel?”

The question raised is about the restoration of the kingdom to Israel. The disciples knew the promises given through the prophets about this restoration (Isaiah 9:6–7; Jeremiah 33:15–17; Ezekiel 37:24–27; Ezekiel 36:24–28). These promises speak of peace, justice, love, forgiveness of sins, mercy, and faithfulness.
