The 144,000 are a group that is described in Revelation 7 and 14.
As we know, Revelation is itself a controversial book, largely because of its style and the language it uses.
Language that is sometimes literal and sometimes figurative or metaphorical. It is hard to know which best fits what is being portrayed.
Some see the 144,000 as being a literal number to be taken as literal Israelites.
Others see them as a symbolic number, and as being spiritual Israelites, meaning they are believers both Jew and Gentile.
Yet others have concluded that they are literally 144,000 yet they are not literal but spiritual Israelites.
What is your take, and why do you think that?
Revelation 7:
2 Then I saw another angel ascending from the rising of the sun, with the seal of the living God, and he called with a loud voice to the four angels who had been given power to harm earth and sea,
3 saying, "Do not harm the earth or the sea or the trees, until we have sealed the servants of our God on their foreheads.
4 And I heard the number of the sealed, 144,000, sealed from every tribe of the sons of Israel:
5 12,000 from the tribe of Judah were sealed,
12,000 from the tribe of Reuben,
12,000 from the tribe of Gad,
6 12,000 from the tribe of Asher,
12,000 from the tribe of Naphtali,
12,000 from the tribe of Manasseh,
7 12,000 from the tribe of Simeon,
12,000 from the tribe of Levi,
12,000 from the tribe of Issachar,
8 12,000 from the tribe of Zebulun,
12,000 from the tribe of Joseph,
12,000 from the tribe of Benjamin were sealed.
Revelation 14:
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.
2 And I heard a voice from heaven like the roar of many waters and like the sound of loud thunder. The voice I heard was like the sound of harpists playing on their harps,
3 and they were singing a new song before the throne and before the four living creatures and before the elders. No one could learn that song except the 144,000 who had been redeemed from the earth.
4 It is these who have not defiled themselves with women, for they are virgins. It is these who follow the Lamb wherever he goes. These have been redeemed from mankind as firstfruits for God and the Lamb,
5 and in their mouth no lie was found, for they are blameless.
It's in reference your take on the seal of Revelation 7 and the 144,000 who receive it. I'm sure you'll have an answer...
