Apocalypse Explained # 428
428. Verse 4. And I heard the number of them that were sealed; a hundred and forty and four thousand, sealed out of every tribe [of the sons] of Israel. "And I heard the number of them that were sealed," signifies the quality of those who are in good separated from the evil; "a hundred and forty and four thousand, sealed out of every tribe [of the sons] of Israel," signifies all who are in truths from good, and therefore in the church of the Lord.
Matthew 24:31
31
He will send out his angels with a great sound of a trumpet, and they will gather together his chosen ones from the four winds, from one end of the sky to the other.
