and it is revealed here in Revelation Scroll Number Six-
Remember what you have (spiritually) received and heard- hold fast and repent (of your spiritual apostasy)...
(Revelation 3:3).

Are there other scrolls in the bible that appear to reveal this? Yes. Here are a few:

Remember Lot's wife
(Luke 17:32).

Now on the first day of the week, very early in the morning, they, and certain other women with them, came to the tomb bringing the spices that they had prepared. But they found the stone rolled away from the tomb. Then they went in and did not find the body of the Lord Jesus. And it happened, as they were greatly perplexed about this, that behold, two men stood by them in shining garments. Then, as they were afraid and bowed their faces to the earth, they said to them- why do you seek the living among the dead? He is not here, but is risen! Remember how He spoke to you when He was still in Galilee, saying- the Son of Man must be delivered into the hands of sinful men, and be crucified, and the third day rise again. And they remembered His words
(Luke 24:1-8).

Then the Jews said- it has taken forty-six years to build this temple, and will You raise it up in three days? But He was speaking of the temple of His body. Therefore, when He had risen from the dead, His disciples remembered that He had said this to them- and they believed the Scripture and the word which Jesus had said
(John 2:20-22).

We give thanks to God always for you all, making mention of you in our prayers, remembering without ceasing your work of faith, labor of love, and patience of hope in our Lord Jesus Christ in the sight of our God and Father, knowing, beloved brethren, your election by God. For our gospel did not come to you in word only, but also in power, and in the Holy Spirit and in much assurance, as you know what kind of men we were among you for your sake. And you became followers of us and of the Lord, having received the word in much affliction, with joy of the Holy Spirit, so that you became examples to all in Macedonia and Achaia who believe. For from you the word of the Lord has sounded forth, not only in Macedonia and Achaia, but also in every place. Your faith toward God has gone out, so that we do not need to say anything. For they themselves declare concerning us what manner of entry we had to you, and how you turned to God from idols to serve the living and true God, and to wait for His Son from heaven, whom He raised from the dead, even Jesus who delivers us from the wrath to come
(1 Thessalonians 1:2-10).

Remember that Jesus Christ, of the seed of David, was raised from the dead according to my gospel, for which I suffer trouble as an evildoer, even to the point of chains- but the word of God is not chained
(2 Timothy 2:8-9).

But you, beloved, remember the words which were spoken before by the apostles of our Lord Jesus Christ- how they told you that there would be mockers in the last time who would walk according to their own ungodly lusts. These are sensual persons, who cause divisions, not having the Spirit
(Jude 1:17-19).

and it is revealed in Revelation Scroll Number Ten-
Behold, I am coming as a thief
(Revelation 16:15).

Are there other scrolls in the bible that appear to reveal this? Yes. Here are a few:

But know this, that if the master of the house had known what hour the thief would come, he would have watched and not allowed his house to be broken into. Therefore you also be ready, for the Son of Man is coming at an hour you do not expect
(Luke 12:39-40).

The thief does not come except to steal, and to kill, and to destroy. I have come that they may have life, and that they may have it more abundantly
(John 10:10).

But concerning the times and the seasons, brethren, you have no need that I should write to you. For you yourselves know perfectly that the Day of the Lord so comes as a thief in the night. For when they say- peace and safety- then sudden destruction comes upon them, as labor pains upon a pregnant woman. And they shall not escape. But you, brethren, are not in darkness, so that this Day should overtake you as a thief. You are all sons of light and sons of the day. We are not of the night nor of darkness. Therefore let us not sleep, as others do, but let us watch and be sober. For those who sleep, sleep at night, and those who get drunk are drunk at night. But let us who are of the day be sober, putting on the breastplate of faith and love, and as a helmet the hope of salvation. For God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ, who died for us, that whether we wake or sleep, we should live together with Him
(1 Thessalonians 5:1-10).

But the Day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat- both the earth and the works that are in it will be burned up. Therefore, since all these things will be dissolved, what manner of persons ought you to be in holy conduct and godliness
(2 Peter 3:10-11).

But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit, keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life. And on some have compassion, making a distinction- but others save with fear, pulling them out of the fire, hating even the garment defiled by the flesh. Now to Him who is able to keep you from stumbling, and to present you faultless before the presence of His glory with exceeding joy, to God our Savior, Who alone is wise, be glory and majesty, dominion and power, both now and forever. Amen
(Jude 1:20-25).
