2 Chronicles 6: 26, 27
26 “When the heavens are shut up and there is no rain because they have sinned against You, when they pray toward this place and confess Your name, and turn from their sin because You afflict them, 27 then hear in heaven, and forgive the sin of Your servants, Your people Israel, that You may teach them the good way in which they should walk; and send rain on Your land which You have given to Your people as an inheritance.
2 Chronicles 7: 12 - 14
12 Then the LORD appeared to Solomon by night, and said to him: “I have heard your prayer, and have chosen this place for Myself as a house of sacrifice. 13 When I shut up heaven and there is no rain, or command the locusts to devour the land, or send pestilence among My people, 14 if My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land.
Joel 2: 12, 13, 17, 18, 21, 23 - 25
12 “ Now, therefore,” says the LORD,
“ Turn to Me with all your heart,
With fasting, with weeping, and with mourning.”
13 So rend your heart, and not your garments;
Return to the LORD your God,
For He is gracious and merciful,
Slow to anger, and of great kindness;
And He relents from doing harm.
14 Who knows if He will turn and relent,
And leave a blessing behind Him—
A grain offering and a drink offering
For the LORD your God?
15 Blow the trumpet in Zion,
Consecrate a fast,
Call a sacred assembly;
16 Gather the people,
Sanctify the congregation,
Assemble the elders,
Gather the children and nursing babes;
Let the bridegroom go out from his chamber,
And the bride from her dressing room.
17 Let the priests, who minister to the LORD,
Weep between the porch and the altar;
Let them say, “Spare Your people, O LORD,
And do not give Your heritage to reproach,
That the nations should rule over them.
Why should they say among the peoples,
‘ Where is their God?’”
The Land Refreshed
18 Then the LORD will be zealous for His land,
And pity His people.
19 The LORD will answer and say to His people,
“ Behold, I will send you grain and new wine and oil,
And you will be satisfied by them;
I will no longer make you a reproach among the nations.
20 “ But I will remove far from you the northern army,
And will drive him away into a barren and desolate land,
With his face toward the eastern sea
And his back toward the western sea;
His stench will come up,
And his foul odor will rise,
Because he has done monstrous things.”
21 Fear not, O land;
Be glad and rejoice,
For the LORD has done marvelous things!
22 Do not be afraid, you beasts of the field;
For the open pastures are springing up,
And the tree bears its fruit;
The fig tree and the vine yield their strength.
23 Be glad then, you children of Zion,
And rejoice in the LORD your God;
For He has given you the former rain faithfully,[d]
And He will cause the rain to come down for you—
The former rain,
And the latter rain in the first month.
24 The threshing floors shall be full of wheat,
And the vats shall overflow with new wine and oil.
25 “ So I will restore to you the years that the swarming locust has eaten,
The crawling locust,
The consuming locust,
And the chewing locust,[e]
My great army which I sent among you.
26 You shall eat in plenty and be satisfied,
And praise the name of the LORD your God,
Who has dealt wondrously with you;
And My people shall never be put to shame.
27 Then you shall know that I am in the midst of Israel:
I am the LORD your God
And there is no other.
My people shall never be put to shame.
