Joel 2:1

1 Sing ye with a trump in Zion, yell ye in mine holy hill. All the dwellers of earth be disturbed; for the day of the Lord cometh, (Sing ye with a trumpet in Zion, yell ye upon my holy hill. All the people of the land be troubled; for the day of the Lord cometh,)

Joel 2:1 Meaning and Commentary

Joel 2:1

Blow ye the trumpet in Zion, and sound an alarm in my holy
mountain
This is spoken to the priests, whose business it was to blow the trumpets for calling solemn assemblies to meet in Zion, the temple built there, called from thence the holy mountain of God. Here the trumpet is ordered to be blown with a broken quivering voice, a tarantantara, to give notice of approaching danger by the locusts, or those enemies signified by them, and to prepare for it, and return to God by repentance; let all the inhabitants of the land tremble;
at the judgments of God coming upon them, and the alarm of them: for the day of the Lord cometh, for [it is] nigh at hand;
the time fixed by him to punish a wicked people, and to pour out his wrath and vengeance on them; the day of his visitation, not in love, but in anger.

Joel 2:1 In-Context

1 Sing ye with a trump in Zion, yell ye in mine holy hill. All the dwellers of earth be disturbed; for the day of the Lord cometh, (Sing ye with a trumpet in Zion, yell ye upon my holy hill. All the people of the land be troubled; for the day of the Lord cometh,)

2 for the day of darknesses and of mist is nigh, the day of cloud and of whirlwind. (These locusts be) As the morrowtide spread abroad on hills, (like) a much people and strong. None was like it from the beginning, and after it shall not be, till into years of generation and of generation. (for the day of darkness and of mist is near, the day of cloud and of whirlwind. These locusts be like the morning spread abroad upon the hills, like a strong, innumerable host, or army. Nothing was ever like them before, and after them, nothing shall ever be like them again.)

3 Before the face thereof shall be fire devouring, and after it shall be burning flame; as a garden of liking the land shall be before them, and wilderness of desert (it) shall be after them, and none is that shall escape them. (At the front, they be like a devouring fire, and at the back, they be like a burning flame; before they come, the land shall be like a Garden of Eden, but after they leave, it shall be a wilderness of the desert, and there is nothing that shall escape them.)

4 The looking of them shall be as the looking of horses; and as horsemen, so they shall run.

5 As the sound of carts on the heads of hills they shall skip; as the sound of the flame of fire devouring stubble, as a strong people made ready to battle. (They shall skip over the hill-tops, sounding like the rattle of carts, and like the flames of fire devouring stubble; they shall come like a strong, innumerable host, or army, prepared to do battle.)
