Who are the 144,000

Revelation 7New International Version (NIV)

144,000 Sealed

7 After this I saw four angels standing at the four corners of the earth, holding back the four winds of the earth to prevent any wind from blowing on the land or on the sea or on any tree. 2 Then I saw another angel coming up from the east, having the seal of the living God.He called out in a loud voice to the four angels who had been given power to harm the land and the sea: 3 “Do not harm the land or the sea or the trees until we put a seal on the foreheads of the servants of our God.” 4 Then I heard the number of those who were sealed: 144,000 from all the tribes of Israel.
