The word "rapture" is not used in the bible, but the concept of Christ gathering the faithful to him is clear in scripture, in direct language and in parable:

1 Thessalonians 4:16-17 For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. 17 After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever.

Matthew 24:31 And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other.

Matthew 25 1-10 “At that time the kingdom of heaven will be like ten virgins who took their lamps and went out to meet the bridegroom. 2 Five of them were foolish and five were wise. 3 The foolish ones took their lamps but did not take any oil with them. 4 The wise ones, however, took oil in jars along with their lamps. 5 The bridegroom was a long time in coming, and they all became drowsy and fell asleep.

6 “At midnight the cry rang out: ‘Here’s the bridegroom! Come out to meet him!’

7 “Then all the virgins woke up and trimmed their lamps. 8 The foolish ones said to the wise, ‘Give us some of your oil; our lamps are going out.’

9 “‘No,’ they replied, ‘there may not be enough for both us and you. Instead, go to those who sell oil and buy some for yourselves.’

10 “But while they were on their way to buy the oil, the bridegroom arrived. The virgins who were ready went in with him to the wedding banquet. And the door was shut.

11 “Later the others also came. ‘Lord, Lord,’ they said, ‘open the door for us!’

12 “But he replied, ‘Truly I tell you, I don’t know you.’

13 “Therefore keep watch, because you do not know the day or the hour.

There is much more, these just came to mind first.
