Ok, I have finally found scriptures specifying heaven, including for those that died prior to Jesus
(Philippians 3:20-21) . . .As for us, our citizenship exists in the heavens, from which place also we are eagerly waiting for a savior, the Lord Jesus Christ, 21 who will refashion our humiliated body to be conformed to his glorious body according to the operation of the power that he has, even to subject all things to himself. . .
Hebrews 11:13-16 “In faith all these died, although they did not get the [fulfillment of the] promises, … now they are reaching out for a better [place], that is, one belonging to heaven. Hence God is not ashamed of them, to be called upon as their God, for he has made a city ready for them.”
Matthew 8:11 “But I tell YOU that many from eastern parts and western parts will come and recline at the table with Abraham and Isaac and Jacob in the kingdom of the heavens.”
These others indicate heaven.
(1 Corinthians 15:50-53) . . .However, this I say, brothers, that flesh and blood cannot inherit God’s kingdom, neither does corruption inherit incorruption. 51 Look! I tell YOU a sacred secret: We shall not all fall asleep [in death], but we shall all be changed, 52 in a moment, in the twinkling of an eye, during the last trumpet. For the trumpet will sound, and the dead will be raised up incorruptible, and we shall be changed. 53 For this which is corruptible must put on incorruption, and this which is mortal must put on immortality. . .
(2 Corinthians 5:8) 8 But we are of good courage and are well pleased rather to become absent from the body and to make our home with the Lord.. . .
(Philippians 1:22-23) . . .Now if it be to live on in the flesh, this is a fruitage of my work—and yet which thing to select I do not make known. 23 I am under pressure from these two things; but what I do desire is the releasing and the being with Christ, for this, to be sure, is far better. . .
(John 14:2-3) . . .In the house of my Father there are many abodes. Otherwise, I would have told YOU, because I am going my way to prepare a place for YOU. 3 Also, if I go my way and prepare a place for YOU, I am coming again and will receive YOU home to myself, that where I am YOU also may be.. . .
(1 Thessalonians 4:13-18) . . .Moreover, brothers, we do not want YOU to be ignorant concerning those who are sleeping [in death]; that YOU may not sorrow just as the rest also do who have no hope. 14 For if our faith is that Jesus died and rose again, so, too, those who have fallen asleep [in death] through Jesus God will bring with him. 15 For this is what we tell YOU by Jehovah’s word, that we the living who survive to the presence of the Lord shall in no way precede those who have fallen asleep [in death]; 16 because the Lord himself will descend from heaven with a commanding call, with an archangel’s voice and with God’s trumpet, and those who are dead in union with Christ will rise first. 17 Afterward we the living who are surviving will, together with them, be caught away in clouds to meet the Lord in the air; and thus we shall always be with [the] Lord. 18 Consequently keep comforting one another with these words.
(John 14:3) . . .Also, if I go my way and prepare a place for YOU, I am coming again and will receive YOU home to myself, that where I am YOU also may be. . .
