'Rejoicing' in the Bible

That your rejoicing may be more abundant in Jesus Christ for me by my coming to you again.

the word of life holding forth, for rejoicing to me in regard to a day of Christ, that not in vain did I run, nor in vain did I labour;

So then, my brothers, keep on rejoicing in the Lord. It is no trouble for me to write the same things to you; indeed, it is for your safety.

Keep on rejoicing in the Lord at all times. I will say it again: Keep on rejoicing!
