Indeed there are; and I'm glad you acknowledge them.
Here are the one's I've found...
Psalm 13:3
Look on me and answer, Lord my God. Give light to my eyes, or I will sleep in death,Psalm 90:5
Yet you sweep people away in the sleep of death— they are like the new grass of the morning:Daniel 12:2
Multitudes who sleep in the dust of the earth will awake: some to everlasting life, others to shame and everlasting contempt.
John 11:12-13
His disciples replied, “Lord, if he sleeps, he will get better.”
Jesus had been speaking of his death, but his disciples thought he meant natural sleep.
1 Corinthians 15:51-52
Listen, I tell you a mystery:We will not all sleep, but we will all be changed—in a flash, in the twinkling of an eye, at the last trumpet.For the trumpet will sound, the dead will be raised imperishable, and we will be changed.
Ephesians 5:14
This is why it is said: “Wake up, sleeper, rise from the dead, and Christ will shine on you.”
1 Thessalonians 4:13
Brothers and sisters, we do not want you to be uninformed about those who sleep in death, so that you do not grieve like the rest of mankind, who have no hope.
Corinthians 15:51-52
Listen, I tell you a mystery:
We will not all sleep, but we will all be changed—in a flash, in the twinkling of an eye, at the last trumpet.
For the trumpet will sound, the dead will be raised imperishable, and we will be changed.”
I don’t know why the “anti-rapturists” keep stumbling over this. Matthew 24-25 speaks of a gathering of peoples.
Some post millenialists see great meaning at the “last trumpet” phrase meaning that the Rapture occurs at the end of the judgment phase just before Christ sets up his Earthly kingdom or perhaps when the 7th trumpet angel sounds his trumpet. Of course there is the yearly “Christ coming in September before Rosh Hashana” crowd.(When the last trumpet is supposed to be blown before that particular Sabbath).
