Revelation 7 Commentary

Angels are summoned to hold back the winds as the seal of God is placed on the foreheads of all the bond-servants, which consecrates them to the Lord and sets them apart. People from all twelve tribes of Israel are sealed, although the makeup of the tribe list has some notable replacements.

People from every nation, tribe, and language stand before the Lamb in the throne room, along with the angels, creatures, and elders. They worship God.

One of the elders explains that the martyrs dressed in white robes who worship God are there in the throne room because they have come out of the great tribulation and have washed their robes white in the blood of the Lamb.
