A strong people set in battle array

Sound an alarm ( Joel 2:5)

Hath anything been like this before?

The army of The Lord!

A fire goes before them and

Behind them a flame (Joel 2:3)

The earth quakes and trembles

Yea, no one will escape

Rend you heart and

Not your garments, (Joel 2:13)

Lo, weep and pray (Joel 2:17)

The Lord is gracious and merciful

Who can abide in His day? (Joel 2:18)

Joel 2:5

Like the noise of chariots on the tops of mountains shall they leap, like the noise of a flame of fire that devoureth the stubble, as a strong people set in battle array. 

Joel 2:3

 A fire devoureth before them; and behind them a flame burneth: the land is as the garden of Eden before them, and behind them a desolate wilderness; yea, and nothing shall escape them. 

Joel 2:13

 And rend your heart, and not your garments, and turn unto the LORD your God: for he is gracious and merciful, slow to anger, and of great kindness, and repenteth him of the evil. 

Joel 2:17

Let the priests, the ministers of the LORD, weep between the porch and the altar, and let them say, Spare thy people, O LORD, and give not thine heritage to reproach, that the heathen should rule over them: wherefore should they say among the people, Where is their God?

Joel 2:11

And the LORD shall utter his voice before his army: for his camp is very great: for he is strong that executeth his word: for the day of the LORD is great and very terrible; and who can abide it
