15 Blow the ram's horn in Jerusalem! Announce a time of fasting; call the people together for a solemn meeting. 16 Gather all the people- the elders, the children, and even the babies. Call the bridegroom from his quarters and the bride from her private room. 17 Let the priests, who minister in the Lord 's presence, stand and weep between the entry room to the Temple and the altar. Let them pray, "Spare your people, Lord ! Don't let your special possession become an object of mockery. Don't let them become a joke for unbelieving foreigners who say, 'Has the God of Israel left them?'"
Matthew Henry's Commentary on Joel 2:15-17
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.
