20 but I will remove far off from you the northern [army], and will drive it into a land barren and desolate, its forepart into the eastern sea, and its hinder part into the western sea; and its stench shall come up, and its ill savor shall come up, because it hath done great things.

Matthew Henry's Commentary on Joel 2:20

Commentary on Joel 2:15-27

(Read Joel 2:15-27)

The priests and rulers are to appoint a solemn fast. The sinner's supplication is, Spare us, good Lord. God is ready to succour his people; and he waits to be gracious. They prayed that God would spare them, and he answered them. His promises are real answers to the prayers of faith; with him saying and doing are not two things. Some understand these promises figuratively, as pointing to gospel grace, and as fulfilled in the abundant comforts treasured up for believers in the covenant of grace.
