Joel 2

The text moves from a local, historical crisis of a locust plague to a theological exposition of God's character and purposes for His people in history and into the future.

• The Lord will be jealous for his land, and pity his people (v. 18).
• I will send you corn, and wine, and oil (v. 19).
• I will remove far off from you the northern army (v. 20).
• I will restore to you the years that the locust hath eaten (v. 25).
• I will pour out my spirit upon all flesh (v. 28).
• Whosoever shall call on the name of the Lord shall be delivered (v. 32).

• Blow ye the trumpet in Zion (v. 1).
• Sound an alarm in my holy mountain (v. 1).
• Turn ye even to me with all your heart (v. 12).
• Rend your heart, and not your garments (v. 13).
• Sanctify a fast (v. 15).
• Gather the people (v. 16).

• The day of the Lord cometh, for it is nigh at hand (v. 1).
• Who can abide it? (v. 11).

• The text describes a devastating locust plague, viewed as the judgment of God upon the nation.
• Matthew Henry observes that the description of the locusts as an 'army' is fitting, as they move with order and efficiency, reflecting the irresistible nature of God's providential judgments.

• The trumpet (שׁוֹפָר [H7782]) was used to call the congregation to battle or religious assembly.
• The priests were central in intercession, standing between the porch and the altar as mediators for the people.

• Joel 2 functions as the pivot of the book, transitioning from the description of the current locust plague to the future, eschatological hope.
• The passage moves from the specific agricultural failure to the national and global cosmic signs of the Day of the Lord.

• Acts 2:16-21 explicitly identifies the events of Pentecost as the fulfillment of the promise in Joel 2:28-32.
• Romans 10:13 quotes Joel 2:32 to emphasize the universal availability of salvation through calling upon the name of the Lord.
• The concept of the 'Day of the Lord' is developed throughout the minor prophets (e.g., Amos 5:18, Zephaniah 1:14-18).

• The description of the land as 'the garden of Eden' (v. 3) contrasts with the 'desolate wilderness' that follows, highlighting the transformative power of judgment.
• The 'Day of the Lord' (vv. 1, 11) is an allusion to the prophetic theme of God's decisive, historical intervention.

• Blow (תָּקַע [H8628]): Indicates a forceful, clanging sound to incite action.
• Trumpet (שׁוֹפָר [H7782]): Specifically the ram's horn, associated with alarm or proclamation.
• Day (יוֹם [H3117]): Often used in Hebrew prophecy to denote not just a 24-hour cycle, but a period of time marked by a specific divine event.
• Great (רַב [H7227]): Emphasizes the abundance, magnitude, and overwhelming scale of the locust army.

• The shift in perspective from the locusts as a natural disaster to the locusts as 'my great army' (v. 25), indicating that God remains the sovereign agent even in the midst of disaster.
• The specific inclusion of all people groups in the promise of the Spirit (v. 29) foreshadows the New Covenant extension to the Gentiles.

• Interpretive Debate: The identity of the 'northern army' (v. 20) is contested. Some scholars interpret this literally as the locusts (as they often arrive from the north in the region), while others view it as a prophetic reference to a human army (Assyria, Babylon, or a future eschatological foe).
• Eschatological Expectation: Matthew Henry and other historic Reformed theologians often view the fulfillment of Joel 2:28-32 as beginning at Pentecost and continuing through the Gospel age. In contrast, other interpretive systems, such as Dispensationalism, often distinguish between the partial fulfillment at Pentecost and a future, literal fulfillment involving the nation of Israel, illustrating a classic tension in eschatological hermeneutics.
