2 Then I saw another Angel rising from where the sun rose, carrying the seal of the Living God. He thundered to the Four Angels assigned the task of hurting earth and sea, 3 "Don't hurt the earth! Don't hurt the sea! Don't so much as hurt a tree until I've sealed the servants of our God on their foreheads!" 4 I heard the count of those who were sealed: 144,000! They were sealed out of every Tribe of Israel: 5 12,000 sealed from Judah, 12,000 from Reuben, 12,000 from Gad, 6 12,000 from Asher, 12,000 from Naphtali, 12,000 from Manasseh, 7 12,000 from Simeon, 12,000 from Levi, 12,000 from Issachar, 8 12,000 from Zebulun, 12,000 from Joseph, 12,000 sealed from Benjamin.

Commentary on Revelation 7:1-8

(Read Revelation 7:1-8)

In the figurative language of Scripture, the blowing of the four winds together, means a dreadful and general destruction. But the destruction is delayed. Seals were used to mark for each person his own possessions. This mark is the witness of the Holy Ghost, printed in the hearts of believers. And the Lord would not suffer his people to be afflicted before they were marked, that they might be prepared against all conflicts. And, observe, of those who are thus sealed by the Spirit, the seal must be on the forehead, plainly to be seen alike by friends and foes, but not by the believer himself, except as he looks stedfastly in the glass of God's word. The number of those who were sealed, may be understood to stand for the remnant of people which God reserved. Though the church of God is but a little flock, in comparison with the wicked world, yet it is a society really large, and to be still more enlarged. Here the universal church is figured under the type of Israel.
