The Bible doesn't say this anywhere. Some interpret it to mean that the dead who make it to Heaven will be reunited. It is noteworthy that not all believe eternity will be spent in Heaven. Revelations specifies that the Earth will be the location of God's Kingdom, and the dead will be resurrected. Some relevant Biblical verses: 1 Corinthians 13:12, "For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known." Matthew 22:31-32, "And after six days Jesus took with him Peter and James, and John his brother, and led them up a high mountain by themselves. And he was transfigured before them, and his face shone like the sun, and his clothes became white as light. And behold, there appeared to them Moses and Elijah, talking with him. And Peter said to Jesus, 'Lord, it is good that we are here. If you wish, I will make three tents here, one for you and one for Moses and one for Elijah.' He was still speaking when, behold, ma bright cloud overshadowed them, and ma voice from the cloud said, 'This is my beloved Son, with whom I am well pleased; listen to him.' When the disciples heard this, qthey fell on their faces and were terrified. But Jesus came and touched them, saying, 'Rise, and shave no fear.' And when they lifted up their eyes, they saw no one but Jesus only." (This strongly indicates that, while dead, Elijah and Moses have retained their appearance and personality. Moreover, they converse.) Ecclesiastes 9:5-6, "For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten. Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion for ever in any thing that is done under the sun." This says that the dead no nothing. John 3:13, "No one has ascended to heaven but He who came down from heaven, that is, the Son of man who is in heaven." This clearly states that no one has died and gone to Heaven. There are many other conflicting quotes on this matter, so it is up to you what to make of them.
