Joel 2:11-15

11The Lord makes his voice heard in the presence of his army. His camp is very large; those who carry out his command are powerful. Indeed, the day of the Lord is terrible and dreadful  — who can endure it?

12Even now — this is the Lord’s declaration — turn to me with all your heart, with fasting, weeping, and mourning.

13Tear your hearts, not just your clothes, and return to the Lord your God. For he is gracious and compassionate, slow to anger, abounding in faithful love, and he relents from sending disaster.

14Who knows? He may turn and relent and leave a blessing behind him, so you can offer a grain offering and a drink offering to the Lord your God.

15Blow the ram’s horn in Zion! Announce a sacred fast; proclaim a solemn assembly.
