Hurt not the earth--7:3.
“ Saying, Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads.”
This was the counter command of the angel of the rising sun to the four angels. The purpose of this sealing, as later seen, is to preserve the holy seed, the true Israel of God, from the judgments about to come upon the earth. It was not exemption from suffering, but from the judgments about to be announced in the opening of the seventh seal. It was a suspension period before the break of fury, signifying the divine protection of the faithful seed, the assurance that no force could bring them ultimate harm.
The sealing in their foreheads was a symbol of an insignia or a mark to save them from slaughter, but not from tribulation, for chapter 2:10 said “ thou shalt suffer tribulation ten days.” But they would survive it; they would be preserved in the midst of it, by a mark to distinguish the true Israel, the holy seed, from old Israel, the fleshly Jew. The old Israel was soon to perish, the new Israel to be preserved; the old Jerusalem was soon destroyed by impending judgments, the new Israel to be sealed for preservation, to survive and flourish as Mount Zion, the city of the living God, the heavenly Jerusalem, the church of the firstborn, sealed on earth and enrolled in heaven. A similar imagery is employed by Jeremiah in foretelling the captivity of Israel in Babylon. (Ezekiel 9:4)
Its history repeats itself in these visions of tribulation in the final destruction of Jerusalem, and of Israel’ s nation. It is noteworthy that in this imagery there was the mark that sealed the servants of God in their foreheads, who worshipped not the beast, in contrast with what was later called the mark of the beast, also received upon their foreheads and in their hands, by those who submitted to the beast--to the decree of the emperor against the worship of the Lamb, and for the worship of the emperor, as set forth in the second series of symbols surrounding the church the Bride of the Lamb. In a similar figure Paul carried the mark of his Lord. (Galatians 6:17)
