Revelation 14:1-2

International Standard Version

The Vision of the New Song on Mount Zion

14 Then I looked, and there was the lamb, standing on Mount Zion! With him were 144,000 people who had his name and his Father’s name written on their foreheads.

² Then I heard a sound from heaven like that of many waters and like the sound of loud thunder. The sound I heard was like harpists playing on their harps.
