'Rejoice' in the Bible

The one who reaps receives wages and gathers fruit for eternal life, in order that the one who sows and the one who reaps can rejoice together.

That one was the lamp [which was] burning and shining, and you wanted to rejoice for an hour in his light.

Truly, truly I say to you, that you will weep and lament, but the world will rejoice; you will become sorrowful, but your sorrow will change to joy.

So you also are experiencing sorrow now, but I will see you again, and your hearts will rejoice, and no one will take away your joy from you.
