'Rejoice' in the Bible

Now I rejoice, not that ye have been grieved, but that ye have been grieved to repentance; for ye have been grieved according to God, that in nothing ye might be injured by us.

I rejoice that in everything I am confident as to you.

For we rejoice when we may be weak and ye may be powerful. But this also we pray for, your perfecting.

For the rest, brethren, rejoice; be perfected; be encouraged; be of one mind; be at peace; and the God of love and peace shall be with you.
