Matthew Poole and continuators on Revelation 7:3

3 Saying Hurt not the earth, nor the sea, nor the trees, until we have sealed the servants of our God in the foreheads .

A Manifest Allusion to Ezek. 9.4. and, as some think, to the Usage of some Eastern Countries, for Masters to set their Names upon the Foreheads of their Slaves, by which they were known to be theirs, as we mark our Sheep, or other Beasts. Men as vainly dispute what this Seal should be, as what the [non-Latin text not transcribed] meant in Ezek. 9. (the Mark set upon those that mourned for the Abominations of Hierusalem.) The Place where they were to be sealed signified the end of their sealing, not so much for confirmation, for which Seals are used, as Notification, to signifie to others they belong to God: So as it was of the same use as the Blood upon the two Side-posts, and the upper Door-posts of the Israelites in Egypt ▪ Exod. 12.13.
