87. It is much the same in the other instances - for example, where it says joy it also says gladness, as in the following examples.
Behold joy and gladness, [people] slaughtering an ox. (Isaiah 22:13)
They will obtain joy and gladness; sadness and groaning will flee. (Isaiah 35:10; 51:11)
Gladness and joy have been cut off from the house of our God. (Joel 1:16)

The fast of the tenth month will become joy and gladness for the house of Judah. (Zechariah 8:19)
So that we may rejoice all our days, make us glad. (Psalms 90:14-15)
Be glad in Jerusalem; rejoice in her. (Isaiah 66:10)
Rejoice and be glad, O daughter of Edom. (Lamentations 4:21)

Joy and gladness will be found in Zion, praise and the voice of song. (Isaiah 51:3)

I will make the voice of joy and the voice of gladness cease, the voice of the bridegroom and the voice of the bride. (Jeremiah 7:34; 16:9; 25:10)

There are other passages as well.
[2] The reason it says both “joy” and “gladness” is that joy has to do with what is good and gladness with what is true, or joy has to do with love and gladness with wisdom. The underlying cause is that joy is of the heart and gladness is of the spirit, or joy arises from our will and gladness from our understanding.
We can see that this also involves a marriage of the Lord and the church from the fact that it speaks of “the voice of joy and the voice of gladness, the voice of the bridegroom and the voice of the bride” (Jeremiah 7:34; 16:9; 25:10; 33:10-11), and the Lord is the bridegroom and the church is the bride. On the Lord as the bridegroom, see Matthew 9:15; Mark 2:19-20; Luke 5:34-35; and on the church as the bride, see Revelation 21:2, 9; 22:17. That is why John the Baptist said, “The bridegroom is the one who has the bride” (John 3:29).
