Joel 2:18
“Then will the Lord be jealous for his land, and pity his people.”
Gather the people, sanctify the congregation, assemble the elders, gather the children, and those that suck the breasts: let the bridegroom go forth of his chamber, and the bride out of her closet.
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?
Then will the Lord be jealous for his land, and pity his people.
Yea, the Lord will answer and say unto his people, Behold, I will send you corn, and wine, and oil, and ye shall be satisfied therewith: and I will no more make you a reproach among the heathen:
But I will remove far off from you the northern army, and will drive him into a land barren and desolate, with his face toward the east sea, and his hinder part toward the utmost sea, and his stink shall come up, and his ill savour shall come up, because he hath done great things.
