Isaiah 35:10 And the ransomed of the Lord shall return,
And come to Zion with singing; with everlasting joy on their heads.
They shall obtain joy and gladness,
And sorrow and sighing shall flee away.

Psalm 51:8 Make me hear joy and gladness,
That the bones You have broken may rejoice.

Isaiah 51:
3 For the Lord will comfort Zion,
He will comfort all her waste places;
He will make her wilderness like Eden,
And her desert like the garden of the Lord;
Joy and gladness will be found in it,
Thanksgiving and the voice of melody.
11 So the ransomed of the Lord shall return,
And come to Zion with singing,
With everlasting joy on their heads.
They shall obtain joy and gladness;
Sorrow and sighing shall flee away.

Jeremiah 31:
7 For thus says the Lord: Sing with gladness for Jacob,
And shout among the chief of the nations; Proclaim, give praise, and say,
O Lord, save Your people, the remnant of Israel!
8 Behold, I will bring them from the north country, nd gather them from
the ends of the earth, among them the blind and the lame, The woman with
child and the one who labors with child, together. A great throng shall return there.
9 They shall come with weeping, and with supplications I will lead them. I will
cause them to walk by the rivers of waters, in a straight way in which they shall
not stumble. For I am a Father to Israel, and Ephraim is My firstborn.
10 Hear the word of the Lord, O nations, and declare it in the isles afar off, and say,
He who scattered Israel will gather him, and keep him as a shepherd does his flock.
11 For the Lord has redeemed Jacob, and ransomed him from the hand of one stronger
than he.
12 Therefore they shall come and sing in the height of Zion, streaming to the goodness
of the Lord—for wheat and new wine and oil, for the young of the flock and the herd;
Their souls shall be like a well-watered garden, and they shall sorrow no more at all.
13 Then shall the virgin rejoice in the dance, And the young men and the old, together;
For I will turn their mourning to joy and will comfort them, and make them rejoice rather than sorrow.

Zechariah 8:19 Thus says the Lord of hosts: The fast of the fourth, the fast of
the fifth, the fast of the seventh, and the fast of the tenth month shall be for
joy and gladness and cheerful feasts for the house of Judah.
Therefore love truth and peace.

Isaiah 61:
1 The Spirit of the Lord God is upon Me,
Because the Lord has anointed Me
To preach good tidings to the poor;
He has sent Me to heal the brokenhearted,
To proclaim liberty to the captives,
And the opening of the prison to those who are bound;
2 To proclaim the acceptable year of the Lord,
And the day of vengeance of our God;
To comfort all who mourn,
3 To console those who mourn in Zion,
To give them beauty for ashes,
The oil of joy for mourning,
The garment of praise for the spirit of heaviness;
That they may be called trees of righteousness,
The planting of the Lord, that He may be glorified.

7 Instead of your shame you shall have double honor,
And instead of confusion they shall rejoice in their portion.
Therefore in their land they shall possess double;
Everlasting joy shall be theirs.

Jeremiah 33:
8 I will cleanse them from all their iniquity by which they have sinned against Me,
and I will pardon all their iniquities by which they have sinned and by which they
have transgressed against Me.
9 Then it shall be to Me a name of joy, a praise, and an honor before all nations of
the earth, who shall hear all the good that I do to them; they shall fear and tremble
for all the goodness and all the prosperity that I provide for it.
10 Thus says the Lord: ‘Again there shall be heard in this place—of which you say,
It is desolate, without man and without beast”—in the cities of Judah, in the streets
of Jerusalem that are desolate, without man and without inhabitant and without beast,
11 the voice of joy and the voice of gladness, the voice of the bridegroom and the voice
of the bride, the voice of those who will say: Praise the Lord of hosts,
For the Lord is good, for His mercy endures forever—
and of those who will bring the sacrifice of praise into the house of the Lord.
For I will cause the captives of the land to return as at the first,’says the Lord.
