Philippians

1:4  Always in every prayer of mine making request for you in all joy.

4:1  Therefore my beloved and longed-for brethren, my joy and crown, so stand fast in the Lord, beloved.

4:4  Rejoice in the Lord always.  Again I say, rejoice.

4:10  But I rejoiced in the Lord greatly that now at last your care for me has flourished again; though you surely did care but you lacked opportunity.

Colossians

1:11  Strengthened in all might, according to His glorious power, for all patience and longsuffering with joy.

1:24  I now rejoice in my sufferings for you, and fill up in my flesh what is lacking in the afflictions of Christ, for the sake of His body, which is the church.

2:5  For though I am absent in the flesh, yet I am with you in spirit, rejoicing to see your good order and the steadfastness of your faith in Christ.

1 Thessalonians

1:6  And you became followers of us and the Lord, having received the word in much affliction, with joy in the Holy Spirit.

2:19  For what is our hope, or joy, or crown of rejoicing?  Is it not even you in the presence of our Lord Jesus Christ at His coming?

2:20  For you are our glory and joy.

5:16  Rejoice always

2 Corinthians

2:3  And I wrote this very thing to you, lest, when I came, I should have sorrow over those from whom I ought to have joy, having confidence in you all that my joy is the joy of you all.

7:4  Great is my boldness of speech toward you, great is my boasting on your behalf.  I am filled with comfort.  I am exceedingly joyful in all our tribulation.

7:7  And not only by his coming, but also by the consolation with which he was comforted in you, when he told us of your earnest desire, your mourning, your zeal for me, so that I rejoiced even more.

7:9  Now I rejoice, not that you were made sorry, but that your sorrow led to repentance.  For you were made sorry in a godly manner, that you might suffer loss from us in nothing.

7:16  Therefore I rejoice that I have confidence in you in everything.

1 John 1:4  And these things we write to you that our joy may be full.

2 John 4  I rejoiced greatly that I have found some of your children walking in truth, as we received commandment from the father.

3 John 3  For I rejoiced greatly when brethren came and testified of the truth that is in you, just as you walk in the truth.

James 1:2  My brethren, count it all joy when you fall into various trials, knowing that the testing of your faith produces patience.

1 Peter 1:8  Whom having not seen, you love.  Though now you do not see Him, yet believing, you rejoice with joy inexpressible and full of glory.

Note:  “Happy” in modern translations is the same word as “blessed,” as in the Beatitudes.  “Blessed” is “above the cares of this life.”  “Joy” is more along the lines of “delighted” or “exceedingly glad.”
