gcall a solemn assembly.
Gather hthe elders
and iall the inhabitants of the land
to the house of the Lord your God,
and cry out to the Lord.

jFor the day of the Lord is near,
and as destruction from the Almighty
 Destruction sounds like the Hebrew for  Almighty
it comes.

Joel 2:12-17

Return to the Lord

12 “Yet even now,” declares the Lord,
lreturn to me with all your heart,
mwith fasting, with weeping, and with mourning;
13and nrend your hearts and not oyour garments.”
Return to the Lord your God,
pfor he is gracious and merciful,
slow to anger, and abounding in steadfast love;
qand he relents over disaster.
14 rWho knows whether he will not turn and relent,
and sleave a blessing behind him,
ta grain offering and a drink offering
for the Lord your God?
15 uBlow the trumpet in Zion;
vconsecrate a fast;
call a solemn assembly;
16gather the people.
wConsecrate the congregation;
assemble the elders;
xgather the children,
even nursing infants.
yLet the bridegroom leave his room,
and the bride her chamber.
17 zBetween the aavestibule and the abaltar
aclet the priests, the ministers of the Lord, weep
and say, “Spare your people, O Lord,
and make not your heritage a reproach,
a byword among the nations.
Or  reproach, that the nations should rule over them

aeWhy should they say among the peoples,
Where is their God?’”

Jonah 3:4-9

4Jonah began to go into the city, going a day’s journey. And he called out, “Yet forty days, and Nineveh shall be overthrown!” 5 afAnd the people of Nineveh believed God. agThey called for a fast and ahput on sackcloth, from the greatest of them to the least of them.

The People of Nineveh Repent

6The word reached
Or had reached
the king of Nineveh, and ajhe arose from his throne, removed his robe, covered himself with sackcloth, akand sat in ashes.
7And he issued a proclamation and published through Nineveh, al“By the decree of the king and his nobles: Let neither man nor ambeast, herd nor flock, taste anything. Let them not feed or drink water, 8but let man and anbeast be covered with sackcloth, and let them call out mightily to God. aoLet everyone turn from his evil way and from apthe violence that is in his hands. 9 aqWho knows? God may turn and relent arand turn from his fierce anger, so that we may not perish.”
