Jonah 3:6

When Mordecai perceived all that was done, Mordecai rent his clothes, and put on sackcloth with ashes, and went out into the midst of the city, and cried with a loud and a bitter cry; And came even before the king’s gate: for none might enter into the king’s gate clothed with sackcloth. And in every province, whithersoever the king’s commandment and his decree came, there was great mourning among the Jews, and fasting, and weeping, and wailing; and many lay in sackcloth and ashes. So Esther’s maids and her chamberlains came and told it her. Then was the queen exceedingly grieved; and she sent raiment to clothe Mordecai, and to take away his sackcloth from him: but he received it not.

But he giveth more grace. Wherefore he saith, God resisteth the proud, but giveth grace unto the humble. Submit yourselves therefore to God. Resist the devil, and he will flee from you. Draw nigh to God, and he will draw nigh to you. Cleanse your hands, ye sinners; and purify your hearts, ye double minded. Be afflicted, and mourn, and weep: let your laughter be turned to mourning, and your joy to heaviness. Humble yourselves in the sight of the Lord, and he shall lift you up.

And I set my face unto the Lord God, to seek by prayer and supplications, with fasting, and sackcloth, and ashes:

And he took him a potsherd to scrape himself withal; and he sat down among the ashes.

And shall cause their voice to be heard against thee, and shall cry bitterly, and shall cast up dust upon their heads, they shall wallow themselves in the ashes: And they shall make themselves utterly bald for thee, and gird them with sackcloth, and they shall weep for thee with bitterness of heart and bitter wailing.

Let the brother of low degree rejoice in that he is exalted: But the rich, in that he is made low: because as the flower of the grass he shall pass away.

O daughter of my people, gird thee with sackcloth, and wallow thyself in ashes: make thee mourning, as for an only son, most bitter lamentation: for the spoiler shall suddenly come upon us.

Woe unto thee, Chorazin! woe unto thee, Bethsaida! for if the mighty works had been done in Tyre and Sidon, which have been done in you, they had a great while ago repented, sitting in sackcloth and ashes.

Woe unto thee, Chorazin! woe unto thee, Bethsaida! for if the mighty works, which were done in you, had been done in Tyre and Sidon, they would have repented long ago in sackcloth and ashes.

Say unto the king and to the queen, Humble yourselves, sit down: for your principalities shall come down, even the crown of your glory.

Wherefore I abhor myself, and repent in dust and ashes.

He putteth his mouth in the dust; if so be there may be hope.

Declare ye it not at Gath, weep ye not at all: in the house of Aphrah roll thyself in the dust.

Be wise now therefore, O ye kings: be instructed, ye judges of the earth. Serve the Lord with fear, and rejoice with trembling. Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him.
