It make be or not be in the Bible but God did Rapture three Biblical persons - Enoch, Ezekial and Jesus so there is precedent.
Matthew 24:36-44 (New International Version © 2010)
36 “But about that day or hour no one knows, not even the angels in heaven, nor the Son,[a] but only the Father. 37 As it was in the days of Noah, so it will be at the coming of the Son of Man. 38 For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; 39 and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man.** 40 Two men will be in the field; one will be taken and the other left. 41 Two women will be grinding with a hand mill; one will be taken and the other left.** 42 “Therefore keep watch, because you do not know on what day your Lord will come. 43 But understand this: If the owner of the house had known at what time of night the thief was coming, he would have kept watch and would not have let his house be broken into. 44 So you also must be ready, because the Son of Man will come at an hour when you do not expect him.
Its clear though by these passages in bold that the Rapture is not a limited event using current numbers over 3.4 billion people will be raptured since its two people noted twice and one was raptured or 50%. Jesus was simple in teachings if He meant limited He would have worded it in a clear way like out of a town one will be taken etc. He clearly wanted us to know that God is not just going to Rapture Christians but children too innocent to be culpable, righteous of other faiths and likely those God finds willing to spare even possibly those without faith.
