And he received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but are not circumcised, in order that righteousness might be credited to them.

Even if I am not an apostle to others, surely I am to you. For you are the seal of my apostleship in the Lord.

Nevertheless, God’s firm foundation stands, bearing this seal: “The Lord knows those who are His,” and, “Everyone who calls on the name of the Lord must turn away from iniquity.”

Then I saw a scroll in the right hand of the One seated on the throne. It had writing on both sides and was sealed with seven seals.

And I saw a mighty angel proclaiming in a loud voice, “Who is worthy to break the seals and open the scroll?”

Then one of the elders said to me, “Do not weep! Behold, the Lion of the tribe of Judah, the Root of David, has triumphed to open the scroll and its seven seals.”

And they sang a new song: “Worthy are You to take the scroll and open its seals, because You were slain, and by Your blood You purchased for God those from every tribe and tongue and people and nation.

Then I watched as the Lamb opened one of the seven seals, and I heard one of the four living creatures say in a voice like thunder, “Come!”

And when the Lamb opened the second seal, I heard the second living creature say, “Come!”

And when the Lamb opened the third seal, I heard the third living creature say, “Come!” Then I looked and saw a black horse, and its rider held in his hand a pair of scales.

And when the Lamb opened the fourth seal, I heard the voice of the fourth living creature say, “Come!”

And when the Lamb opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony they had upheld.

And I watched as the Lamb opened the sixth seal, and there was a great earthquake, and the sun became black like sackcloth of goat hair, and the whole moon turned blood red,

And I saw another angel ascending from the east, with the seal of the living God. And he called out in a loud voice to the four angels who had been given power to harm the land and the sea:

When the Lamb opened the seventh seal, there was silence in heaven for about half an hour.

They were told not to harm the grass of the earth or any plant or tree, but only those who did not have the seal of God on their foreheads.
