Each of these 144,000 has two names inscribed on the forehead: 1. the name of the Lamb (Jesus Christ), 2. the name of the Lamb’s Father. In Revelation 7:3–4 the 144,000 received an undefined seal on their foreheads. It would appear that our present verse tells us that the seal of Revelation 7:3 was the name of the Lamb and the name of the Lord God. The point then is that the Lord has laid his claim on his chosen.
1 Then I looked, and behold, on Mount Zion stood the Lamb, and with him 144,000 who had his name and his Father’s name written on their foreheads.
