2Ch 20:3, Ezr 8:21-23, Neh 9:1-3, Dan 9:3-5, Joe 2:12, Jon 3 | ESV | STEP | Then Jehoshaphat was afraid and set his face to seek the Lord , and proclaimed a fast throughout all Judah .

21 ^cThen I proclaimed a fast there, at the river ^dAhava, that we might humble ourselves before our God, ^eto seek from him a safe journey for ourselves, our children, and all our goods. 22 For I was ashamed to ask the king for a band of soldiers and horsemen to protect us against the enemy on our way, since we had told the king, ^f“The hand of our God is for good on ^gall who seek him, and the power of his wrath is against all who forsake him.” 23 So we fasted and implored our God for this, and he listened to our entreaty.

Nehemiah 9:1-3

The People of Israel Confess Their Sin

1 Now on the twenty-fourth day of ^hthis month the people of Israel were assembled ⁱwith fasting ^jand in sackcloth, ^kand with earth on their heads. 2 ^lAnd the Israelites ^{▼▼Hebrew the offspring of Israel} separated themselves from all foreigners and stood and confessed their sins and the iniquities of their fathers. 3 ⁿAnd they stood up in their place and read from the Book of the Law of the Lord their God for a quarter of the day; for another quarter of it they made confession and worshiped the Lord their God.

Daniel 9:3-5

3 Then I turned my face to the Lord God, seeking him by ^oprayer and pleas for mercy with fasting and sackcloth and ashes. 4 I prayed to the Lord my God and ^pmade confession, saying, ^q“O Lord, the ^rgreat and awesome God, who ^skeeps covenant and steadfast love with those who love him and keep his commandments, 5 ^twe have sinned and done wrong and acted wickedly ^uand rebelled, turning aside from your commandments and rules.

Joel 2:12

Return to the Lord

12 “Yet even now,” declares the Lord,
^v“return to me with all your heart,
^wwith fasting, with weeping, and with mourning;

Jonah 3

Jonah Goes to Nineveh

1 Then the word of the Lord came to Jonah the second time, saying, 2 “Arise, go to ^xNineveh, that great city, and call out against it the message that I tell you.” 3 So Jonah arose and went to Nineveh, according to the word of the Lord. Now ^yNineveh was an exceedingly great city, ^{▼▼Hebrew a great city to God} three days’ journey in breadth. ^{▼▼Or a visit was a three days’ journey} 4 Jonah began to go into the city, going a day’s journey. And he called out, “Yet forty days, and Nineveh shall be overthrown!” 5 ^abAnd the people of Nineveh believed God. ^acThey called for a fast and ^adput on sackcloth, from the greatest of them to the least of them.

The People of Nineveh Repent

6 The word reached ^{▼▼Or had reached} the king of Nineveh, and ^afhe arose from his throne, removed his robe, covered himself with sackcloth, ^agand sat in ashes. 7 And he issued a proclamation and published through Nineveh, ^ah“By the decree of the king and his nobles: Let neither man nor ^aibeast, herd nor flock, taste anything. Let them not feed or drink water, 8 but let man and ^ajbeast be covered with sackcloth, and let them call out mightily to God. ^akLet everyone turn from his evil way and from ^althe violence that is in his hands. 9 ^amWho knows? God may turn and relent ^anand turn from his fierce anger, so that we may not perish.”

10 When God saw what they did, ^aohow they turned from their evil way, ^apGod relented of the disaster that he had said he would do to them, and he did not do it.
